Problems solved by technology
The existing relay protection device is equipped with a box, and one side of the box is equipped with a socket. Because the heat at the socket end is serious, and the socket on one side of the box is easily squeezed by the wall, the plug-in wire is also easy to cause extrusion. , leading to a reduction in the service life of the differential line and the socket, resulting in a reduction in the working stability of the relay, so it is urgent to develop a relay protection device to solve the problems in the prior art

The invention provides a relay protection device. The relay protection device comprises a box body, wherein a plurality of sockets are mounted on one side of the box body; an upper baffle and a lowerbaffle are further installed on one side of the box body; a limiting plate is mounted at the upper end of the lower baffle; a guide shaft sleeve is mounted on the upper baffle; a shielding plate penetrates through the guide shaft sleeve; a containing cavity is defined by the shielding plate, the box body, the upper baffle and the lower baffle; a handle is installed at the upper end of the shielding plate; the limiting plate is installed at the end, away from the box body, of the lower baffle; the shielding plate is arranged on the side, close to the box body, of the limiting plate, a pluralityof through holes are formed in the upper baffle, and plug wires are inserted into the sockets and penetrate through the through holes. The service life of the plug wire on one side of the relay protection box can be effectively prolonged, and the stability of relay protection is improved.
Description
technical field [0001] The invention relates to a relay protection device. Background technique [0002] In order to ensure that the equipment on the power supply line can operate normally and ensure normal power transmission and power supply, it is necessary to regularly check the equipment on the power supply line. The relay protection device is used in the power system. When the power components in the power system or the power system itself have a fault that endangers the safe operation of the power system, the relay protection device is used to send a warning signal to the operator on duty, or directly to the controlled An automated measure and device in which a circuit breaker issues a trip command to terminate the development of these events. The existing relay protection device is equipped with a box, and one side of the box is equipped with a socket. Because the heat at the socket end is serious, and the socket on one side of the box is easily squeezed by the wall,...
