Abstract

The invention discloses a humidity relay protector used in a transformer box. The humidity relay protector used in a transformer box comprises a first lead, a metal pin, a second lead, a power connector, Load connectors, relay protection devices, low-voltage power supply positive connectors, low-voltage power supply negative connectors, the relay protection device is equipped with power connectors, load connectors, low-voltage power supply positive connectors, low-voltage power supply negative connectors, and metal pins. The positive connector is connected to one of the metal pins through the second lead, and the negative connector of the low-voltage power supply is connected to the remaining metal pins through the first lead. , will not be deformed, does not need frequent maintenance, reduces the number of maintenance, and reduces the workload.

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 ...
