Forest fire trip test platform for transmission line

[0017] see figure 1 , figure 1 Shown is a specific embodiment of the transmission line mountain fire tripping test platform of the present invention. The voltage regulator 1 of this embodiment adopts the TDGC type contact voltage regulator produced by China Hubei Shaoxin Special Electric Co., Ltd., with a rated capacity of 30kVA, a rated input voltage of 380V, and a rated output voltage of 0-420V; the transformer 2 adopts China Hubei Shaoxin The YD (CQ) test transformer produced by Special Electric Co., Ltd. has a rated capacity of 30kVA, a rated output voltage of 0.4kV, and a rated output voltage of 100kV; the resistor 3 is a RESW water resistor produced by Hunan Huicui Electric Power Technology Co., Ltd. The value is 50kΩ; electrode 4 and ground electrode 5 are any one of the ELL type wire-wire electrode, ERR type rod-rod electrode and ERP type rod-plate electrode produced by Hunan Huicui Electric Power Technology Co., Ltd., China, all of the above The ELL type wire-wire electrode or the ERR type rod-rod electrode or the ERP type rod-plate electrode have an air gap with adjustable gap. Described voltage regulator 1, transformer 2, resistance 3, electrode 4, grounding electrode 5 press the technical solution of the present invention above, refer to figure 1 The block diagrams shown are sequentially connected in series. Wherein the output terminal of the voltage regulator 1 is connected to the input terminal of the transformer 2 . The output terminal of transformer 2 is connected to electrode 4 through resistor 3 . The electrode 4 and the ground electrode 5 are connected in the form of a line-line electrode with an adjustable air gap.

[0018] The transmission line mountain fire tripping test platform of the present invention with the above-mentioned structure has been proved to be effective through tests, has the characteristics of simple operation, safety and reliability, and is easy to control, and fully meets the design requirements.
