GB/T 4585-2004 Artificial pollution test for high voltage insulators for AC systems

This standard applies to the determination of power frequency withstand characteristics of porcelain and glass insulators used outdoors and exposed to polluted atmospheres in AC systems with a maximum system voltage range of 1kV to 765kV. These tests cannot be directly applied to oil-coated insulators and special types of insulators (insulators with semi-conductive glaze or insulators covered with any organic insulating material).

GH/T 4585-2004/TFC:80507;1991 This standard is equivalent to 1ECC537:191 Artificial pollution test for commercial pressure products for AC systems (English version): For convenience, the following amendments are made to the standard: 1.) Use "\" as the decimal point, except for 1F057,159.
This standard replaces (3/T15A5.1-19) AC system with high pressure products, the test method for the building is based on GB/ GB/T4585-1:51 AC high voltage, solid layer method. This standard is the same as GB/T4585.1-4 and B/T485.2: The current requirements for the test electrode are the same as GB/T4585.1-4 and B/T485.2, and the circuit current is not less than 0. This standard specifies that the constant current is related to the current ratio of the battery. When the current ratio changes between 1nV and 5mm, the circuit current should change between 15A and 15A. This standard stipulates that the test of the green salt dew method should be carried out at the bottom of the test (the 16th item should be painful). GB/T4555.1 yuan.
GB/T4533.2 stipulates that the quantitative method includes quantitative removal method, and the first 4 standards stipulate the method. -GB/T4365.2 has a kind of pollutant liquid with a high sensitivity of 1% to 2% of the pollutants, one of which is a highly sensitive material. This standard stipulates that there are 2 kinds of pollutants, among which, the difference between the 2 kinds and GB/T4555.2 contains The materials are mulberry and kaolin dispersed oxide, and the other is kaolin (or stone powder). The appendix A of this standard is limited to the list of materials except D. The standard is issued by China Energy Industry Association. The main body of the national standard is: National Chemical Technology Committee, the drafting unit: Xidian Yili Research Institute, Wuhan High Voltage Research Institute, Chongqing University. The main drafters of this standard are: Dazhi, Guan Guangya, Yao Xingliang, Qiu Chuya. The standard sections represented by this standard are: G3/T 4A5,—384,GH/T 45&5.2--19!-1 Scope
GB/T4585—2004/1EC60507,1991 Artificial pollution test for high-voltage insulators for converter systems Section 1 General
This standard is applicable to converter systems with high voltages of 1kV-765kV and is used for the determination of the resistance characteristics of glass insulators in the presence of low-voltage pollutants in the atmosphere. This test method is not applicable to small oil-fired insulators and insulators of the same type as semi-insulated insulators, and is more suitable for insulators with red insulating material particles.
2 This standard specifies the artificial pollution test procedures for insulators of canal lines, substations, traction lines and bushings. 3 Definitions
