A lock control module

Abstract

The invention discloses a lock control module. The lock control module comprises a voltage acquiring unit, an identification unit, a driving unit, a motor, a transmission unit and a lock body. When the identification unit judges that voltage acquired by the voltage acquiring unit is larger than a preset blocked voltage threshold value, a lock closing signal is transmitted to the driving unit, the driving unit receives the lock closing signals and drives the motor to perform lock closing work, the motor is powered on and drives the transmission unit to move, and the transmission unit drives a lock to be closed. When there is no electricity in a circuit, it can be detected that the electric power circuit is live and a grounding switch is turned on under the situation that a circuit breaker is in an open position and electricity is delivered in the electric power circuit reversely, a short-circuit grounding fault and other faults caused when the grounding switch is turned on by mistake are prevented, power supply safety is guaranteed; the transmission unit can be controlled by the driving unit to open the lock when the acquired voltage is not larger than the preset blocked voltage threshold value, and the lock can be opened fast.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a lock control module. Background technique [0002] In the hand-to-hand mutual supply wiring power supply system, the high-voltage switchgear is a very important power receiving and distribution equipment. In order to ensure the safety of power supply, it is clearly stipulated that the high-voltage switchgear must have the "five prevention" functions, that is: to prevent wrong opening and closing of the circuit breaker; to prevent With load opening and closing isolating switch; prevent charged from hanging (closing) grounding wire (grounding switch); prevent power transmission with grounding wire; prevent accidental entry into charged interval. [0003] In the "five preventions", to prevent live connection (closing) the grounding wire (grounding switch), it is necessary to judge whether it is charged by opening and closing the circuit breaker. Only when the circuit breaker is i...

Problems solved by technology

In the hand-to-hand mutual supply wiring power supply system, sometimes the circuit breaker of the feed switch cabinet is in the open state, but there is still a situation of reverse power transmission, which is not really dead. In this case, once the grounding switch is closed, it will Cause short-circuit ground fault, it is difficult to ensure the safety of power supply
