Abstract

The invention discloses a series voltage-dividing type discharging device, which comprises a main circuit and a trigger circuit. The main circuit comprises a current-limiting resistor RCL1, a steady-state voltage-dividing resistor RL1, a voltage-dividing diode DC1 and a conversion control switch VC1; and one end of the current-limiting resistor RCL1 is connected with one end of the steady-state divider resistor RL1 and the anode of the divider diode DC1, the other end of the steady-state divider resistor RL1 is connected with one end of a primary winding N1 of the sampling transformer T, the cathode of the divider diode DC1 is connected with one end of the conversion control switch VC1, the other end of the conversion control switch VC1 is connected with one end of a secondary winding N3 of the sampling transformer T, the control end of the conversion control switch VC1 is connected with the trigger circuit, and the trigger circuit is connected to the two ends of the secondary winding N3 of the sampling transformer T. The terminal voltage of the sampling transformer can be reduced, the winding turns and the iron core weight of the sampling transformer are reduced, and the material cost of the discharge coil is reduced.

Description

technical field [0001] The present invention relates to the technical field of discharge devices, and more specifically relates to a series voltage-dividing discharge device. Background technique [0002] The discharge coil is a discharge device specially designed for power capacitors. At present, the discharge coils widely used are inductive structures, which are similar to the structures of transformers and inductive voltage transformers. [0003] The structure of the inductive discharge coil is as follows figure 1 As shown, it consists of three parts: primary winding N1, secondary winding N2 and iron core. In application, the primary winding is connected in parallel with the compensation capacitor C of the power system, and the secondary winding outputs 100V AC voltage for operation monitoring and relay protection. The output capacity of the secondary winding is 100VA. [0004] The working state of the discharge coil is divided into two working modes: stable state and...
