Abstract

The invention belongs to the technical field of relay protection device module design, and in particular, relates to a verification device for a relay protection device and a verification method thereof. The verification device comprises a direct-current power supply, a three-path variable alternating-current current source, a one-path variable alternating-current voltage source, a wiring port group of a to-be-verified protection device, a switch assembly, a variable alternating-current current source knob, a protection node action indicating lamp group, a variable alternating-current voltageknob, a grounding port, a grounding wire and a plurality of wires, wherein the direct-current power supply, the three-path variable alternating-current current source and the one-path variable alternating-current voltage source are respectively connected with configuration ports of the wiring port group of the to-be-verified protection device; the variable alternating current source knob is connected with the three-path variable alternating current source; the variable alternating-current voltage knob is connected with a variable alternating-current voltage source; the protection node action indicating lamp group is connected with the configuration ports of the wiring port group of the to-be-verified protection device.

Description

technical field [0001] The invention belongs to the technical field of module design of an electrical relay protection device, and in particular relates to a verification device for a relay protection device and a verification method thereof. Background technique [0002] In the plant power system of units 3 and 4 of a nuclear power plant, the relay protection device can respond to the fault of the plant power bus, and act on the circuit breaker quickly, accurately and selectively to cut off the faulty equipment and ensure the reliable operation of the system. The factory power relay protection devices are divided into transformer comprehensive protection devices, motor protection comprehensive protection devices, differential protection comprehensive protection devices and other protection devices, with a total of about 400 sets. The verification of protection devices is an important task of relay protection in power plant overhaul. In the actual verification process, due t...
