三、工作原理
本测试仪是在相距(6.0±0.1)mm 或(6.35±0.1)mm 的两电极上，按试验方法规定的规律（见试验程序
表），由间歇到连续地施加 12.5kV 工作电压和(10～40)mA 的电弧电流，直至试样失效。记下从试验开始
到试样失效的总时间（s），即为该试样的耐电弧。试验电压的产生是由 220V 交流电压经调压器 T5，再由
高压试验变压器 T4 而产生。试验电压 12.5kV 由调压器 T5 调节获得。试验电流的大小和通断时间，PLC
控制接在调压器 T5 和高压试验变压器 T4 之间的四路固态继电器及中间继电器开关和串联电阻而获得。

First, an overview
The arc resistance tester is designed ａnd manufactured according to the requirements of GB/T 1411-2002 "high pressure low current arc discharge test" (equivalent IEC 61621-1997) ａnd ASTM D495, ａnd it is in conformity with the test methods of IEC 149, UL 746A ａnd so on. The instrument is supervised by the National Standards Committee on insulation materials.
It is mainly used for the electric arc resistance of electrical, resin adhesive, insulating varnish, laminated plate ａnd copper clad plate for electrical, electrical ａnd electrical appliances ａnd other industries.

10 experimental current: 10mA - 20mA - 30mA - 40mA
11 Power: 220V/ 50Hz
Three. The principle of work
The tester is tested on a two electrode with a distance of (6 + 0.1) mm or (6.35 + 0.1) mm according to the test procedure.
The 12.5kV voltage ａnd (10~40) mA arc current will be applied intermittently to continuously until the specimen fails. Note from the start of the experiment
The total time (s) of specimen failure is the arc resistance of the specimen. The test voltage is generated by 220V alternating voltage through voltage regulator T5, ａnd then by
High voltage test transformer T4 is produced. The test voltage 12.5kV is obtained by adjusting the regulator T5. The size of the test current ａnd the breaking time, PLC
Control is connected to four solid state relays connected to voltage regulator T5 ａnd high voltage test transformer T4, ａnd intermediate relay switches ａnd series resistors are obtained.
