Why Guangzhou Residents "Change Color"

“The villagers stopped the construction machinery from entering the market and blocked it for 18 days.” Yesterday, the person in charge of the construction of the 500kV transformer substation in Kapok, Guangzhou, told reporters. It is reported that residents are opposed to making the construction of substations in Guangzhou difficult, and Guangzhou currently plans to build substations with 30% “difficulty”. Experts cracked the residents' "scent of electricity and electricity" pointed out that electromagnetic radiation is not as good as mobile phones. China's electromagnetic radiation standards are stricter than WHO standards.

For equipment such as high-voltage transmission lines, transformers, and general household appliances that are not designed to radiate electromagnetic waves, radiation under normal use conditions will not cause any harm to the human body and should not be feared. "Transmission of electromagnetic waves 'radiation' is not even comparable to our daily use of mobile phones." Experts told reporters.

Doubt:

Electromagnetic wave "radiation" is not as good as mobile phones

The experts of the Squirrel Association have eliminated public misunderstandings about electromagnetic radiation. Electromagnetic radiation, as the name implies, is electromagnetic radiation. The oscillating electric and magnetic fields propagate in the form of waves in space to form electromagnetic waves, X-rays, ultraviolet rays, infrared rays, and microwaves. There are radio waves that are electromagnetic waves.

So, electromagnetic waves have no possible harm to the human body?

For longer-wavelength radio waves and long-wave radios, including broadcasting (FM/AM), high-voltage transmission lines and transformers (50Hz), and most home appliances (50Hz), the danger of induced currents is a concern. The conductor generates an induced electromotive force and induced current in an alternating electromagnetic field, and the human body can be regarded as a conductor, and an induced current is also generated in the electromagnetic field. Although the induction current also has a thermal effect (induction cooker), this thermal effect does not cause much influence on the human body in a normal environment.

However, the normal operation of the human nervous system and internal organs requires the exchange and control of bioelectric signals. If the induced current exceeds a certain level of strength, it may interfere with the nervous system and internal organs and cause people to feel uncomfortable. However, the effect of current on the human body needs to be higher than a certain threshold. Below the threshold, the human body cannot feel it.

China's electromagnetic standards are stricter than the WHO standards

"Our country's electromagnetic radiation standards are more stringent than the World Health Organization recommended standards. For example, the power frequency electric field requirement of the World Health Organization is 5000 volts/meter, and our country is 4000 volts/meter. The power frequency magnetic field is about 0.2 milli-Tesla. Our country is 0.1 millitesla.” Shi Yuzhu, a professor at the China South Electric Power Design Institute, told reporters, “The substation in Guangzhou has no problems outside the wall and will not be harmful to the human body.”

According to reports, the standards of the World Health Organization are recommended by hundreds of experts in more than 60 countries and have been developed through various studies of pathology and human cells. "As long as wires and power stations that meet WHO's recommended standards do not have any impact on the public, the public should trust the judgment of the authorities."

survey:

30% of proposed substations have been obstructed due to pre-existing "difficult births"

It is difficult to build substations in Guangzhou, and 30% of the proposed substations are difficult to produce. According to relevant parties, in the past two years, the more prominent problems have come from the opposition of nearby residents. Taking the Tongdewei Substation as an example, the Tongdewei ACV discussed the matter several times and eventually reached a stalemate.

Han Zhipeng, director of the Tongdewei Association Advisory Committee and member of the Guangzhou Municipal CPPCC, once said that since he took the position of director of the Tongde Encirclement Committee, he deeply felt that it was not easy for the government to engage in substation construction, and some residents were caught in the “change in electricity”. Misunderstanding.

Last year, the Guangzhou Municipal Government's executive meeting reviewed and approved the "Guangzhou City, Accelerating the Construction of Power Grids."

It is understood that during the “Eleventh Five-Year Plan” period, the city needs to build 98 substations with 110 kV and above. Because the work in the previous stage was blocked, only 69 transformer substations were actually put into operation, and the realization rate of grid planning was only 70%.

The Guangzhou Power Supply Bureau plans to complete the kapok project by September 30 this year. After the project is completed, it will become the sixth 500 kV substation in Guangzhou and will become the main power source in Tianhe District, Yuexiu District and Baiyun District. Occupying 43.6% of the total electricity demand in Guangzhou, Guangzhou became the largest substation in Guangzhou. However, the opposition of the nearby villagers has become the biggest problem for the completion of the substation on schedule.

Grab the progress: lean on the shoulders to carry the supplies up the mountain

Yesterday, at 11 o'clock in the day, the building construction site of the Luogang section of the kapok power transmission line project was still under construction. The electric construction workers were still erecting wires. The steel bars on the ground and the tower erected in mid-air were sun-baked in the hot sun. The surface temperature reached 70 to 80 degrees Celsius. The reporter touched it and quickly retracted his hand. Workers working on the tower base are either sitting or standing on a steel frame and screwing them for a few hours. To avoid being burned, they wore thick overalls and canvas gloves.

In Conghua Kapok power transmission line project Conghua section. Workers are moving construction materials to the construction site on the top of the mountain. Since Conghua built the first international equestrian field in the country and it is an epidemic-free area according to international standards, it must have no horses in Conghua. Conghua is a mountainous area with seven hills and one water and two fields. There are many cliff trenches along the high-voltage power transmission lines. All steel, wire rods, tools, cement, gravel, and water for mixing concrete must be transported to the scene over mountains. Can not use horses and supplies, construction units use the method of transporting goods by cableway, and if there is no cable transport conditions, it uses human transport, a bag of sand, cement, a strip of tower materials rely on the human back up the mountain.

Difficulties in construction: villagers are unhappy about compensation for radiation

“Taki has been erected. To build the line, the villagers stopped the construction and parked the car on the construction road. The stop is 18 days.” At the construction site of the kapok transportation power project, the relevant person in charge of the construction of the tower foundation in Luogang District The construction process encountered difficulties in construction.

According to reports, there are three main reasons for impeding construction: dissatisfaction with demolition compensation, fear of electromagnetic radiation, and concern that feng shui is not good. In order to obtain high compensation, some villagers temporarily reconstructed or erected illegal constructions, proposed unreasonable requirements, and blocked construction on this ground. Difficulties in construction and the use of electricity by residents to make way for the two major factors leading to kapok substation "difficulty", the construction time will be extended by 3 months, is expected to be completed on September 30.

"The 500 kV kapok substation power transmission and transformation project is one of the main power receiving terminals of the 'West Power East Transmission' project in Guangdong Province and is scheduled to be put into production on September 30, 2013." 500 kV kapok power transmission and transformation project owner Project Manager Zhou Jian introduced the reporter. At present, the kapok power transmission and transformation project is being constructed in addition to the substation located in Taihe Town, Baiyun, and the access and output lines of Tianhe, Luogang, Baiyun, Zengcheng and Conghua are under intense development.

It is reported that the partial structural power shortage in Guangzhou power grid is the biggest obstacle to the current reliable supply of power. At present, there are only five 500 kV substations in Guangzhou, and 60% of the city's electricity is imported from the outside. If there is a problem with a 500 kV substation, the impact will be enormous.

It is reported that starting in September of this year, the central area of ​​Guangzhou will be gradually connected to kapok new power supply, when the original substation will be out of power for 10 to 20 days. The power supply bureau will provide power to the residents through power transfer. As long as there are no unexpected incidents such as external damage, residents will not be affected by power outages.
