Abstract

The invention discloses a relay protection device, and relates to the technical field of relay protection devices. The relay protection device comprises a relay box body, a closing device, a heat dissipation device, a sealing device, a dust collection device, first self-locking universal wheels, a damping device and a relay, the relay box body is horizontally arranged, the closing device is arranged in the relay box body, and the heat dissipation device is arranged outside one side of the relay box body. The sealing device is arranged in the relay box body, the dust collection device is arranged above the first self-locking universal wheel, the first self-locking universal wheel is horizontally arranged, the damping device is arranged in the relay box body, and the relay is arranged in thedamping device. The temperature of the relay can be kept within a certain numerical value through the heat dissipation device, so that the relay is not damaged, the service life is prolonged, a relaycircuit can be prevented from being corroded after the interior of the relay box body is dedusted through the dust collection device, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of relay protection devices, in particular to a relay protection device. Background technique [0002] The relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. When applied to some large-scale equipment, due to the many and complex circuits, the relays are scattered throughout the equipment, which will bring great inconvenience to the maintenance and protection of the relays. If they are not protected in time, it is easy to affect the performance of the...
