The electrical schematic diagram of mine flameproof vacuum feed switch is shown in Figure 3. 3.2.1 the principle diagram of the total leakage protection system based on additional DC detection additional DC power detection leakage protection is shown in Figure 3, which is mainly composed of three-phase reactor and synchronous transformer T3, zero sequence reactor and zero sequence transformer T2, filter circuit composed of resistance and capacitance, and DC power source. Detect the change of the insulation resistance of the power grid to the ground through the DC power supply attached to the RL channel of the module. When the DC voltage is constant, the measured resistance value changes. When the insulation resistance drops to the action value specified in Table 1, the PLC program call is interrupted for immediate output to make the relay act, and its normally open contact connects the shunt tripping coil of the feeder switch to trip the switch, so as to realize leakage protection, and visually display the resistance value to the ground through the LCD. The additional DC power detection leakage protection system has the advantages of comprehensive protection and no dead zone action, but it also has the disadvantages of non selective action and long action time. For 1140V level, the leakage action time of 1K is not more than 30ms. The selective leakage
