Abstract

The invention belongs to the technical field of electricity, and particularly relates to a relay protection tripping circuit terminating device for a nuclear power station. The device comprises a cover plate, a magnetic attraction end interface, an end interface spring contact, a spring terminating base, a display diode and a terminating wire, wherein the inner surface of the cover plate is provided with the magnetic attraction end interface, the middle portion of the magnetic attraction end interface is connected through the display diode, the cover plate is connected with the spring terminating base, the upper surface of the spring terminating base is provided with the end interface spring contact, and the lower part of the end interface spring contact is connected with the terminating wire. The terminating device has waterproof, dustproof and anti-creeping functions, is simple in structure, small in size and convenient to install and use, can be widely applied to a nuclear power station generator transformer protection system device, can reduce working time and human errors, and has good popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a relay protection trip circuit termination device for nuclear power plants. Background technique [0002] The safe operation of the relay protection system is the most important security guarantee of the power system, and the safe operation of related equipment in the relay protection system is especially important. Due to the particularity of equipment such as relay protection devices, a "terminating device" must be designed on the trip circuit, which is an important means of ensuring the safe operation of the relay protection system. The termination device is a disconnection point visible to the naked eye, which is convenient for operators to judge whether the trip circuit of the relay protection device can be connected to the trip coil of the switch, which provides great convenience for maintenance and operation, but also makes the protection of the substation...
