Description

Technical Field

[0001] The utility model belongs to the technical field of relays, and in particular relates to a relay base. Background Art

[0002] Currently, the automatic control functions of various devices in large hydropower stations during power generation are primarily implemented through relays. Relay operation is primarily controlled by a programmable logic controller (PLC), which controls the on / off state of the circuit by controlling the relay coil. Furthermore, when the relay coil reaches its rated voltage, it activates, shifting the normally open and normally closed nodes, thereby providing control, expanding the control range, and amplifying the signal.

[0003] However, there are currently numerous relays in the control cabinets of various devices, and their installation locations vary, making inspection and monitoring difficult. In addition, when the voltage across the relay meets the relay indication lighting voltage but does not meet the coil action voltage, the relay coil cannot operate and cannot perform related control actions. This situation is highly hidden and will greatly endanger the stability of the control system. At the same time, when handling this situation, maintenance personnel need to check all components in the circuit one by one until the faulty relay is located, which will undoubtedly increase the time spent on fault location.
