Abstract

The invention discloses a humidity relay protector used for a power transformation box. The protector includes a first lead, two metal pins, a second lead, a power connector, a load connector, a relayprotection device, a low voltage power source positive terminal and a low voltage power source negative terminal. The relay protection device is provided with the power connector, the load connector,the low voltage power source positive terminal and the low voltage power source negative terminal. The low voltage power source positive terminal is connected to one of the metal pins through the second lead. The low voltage power source negative terminal is connected to the rest metal pin through the first lead. The two metal pins are disposed on the same level. Pulling ropes and balancing weights are adopted for restoring. No deformation is caused and no frequency maintenance is needed. Maintenance frequency is reduced and work load is reduced.

Description

technical field [0001] The invention relates to a humidity relay protector used in a transformer box, which belongs to the field of power distribution. Background technique [0002] Relay (English name: 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 (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). 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. [0003] The substation box is already an indispensable equipment in daily life. It is often ...
