Electronic lock control circuit for high-voltage protection and high-voltage electrical control cabinet
The invention discloses an electronic lock control circuit for high-voltage protection, which is used for controlling opening and closing of an electronic lock on a high-voltage electrical control cabinet, the high-voltage electrical control cabinet is provided with a power supply input interface and a power supply output interface, and a main circuit breaker controls on-off of an electric loop between the power supply input interface and the power supply output interface. A detection point of the electronic lock control circuit is connected with the power input interface through the main circuit breaker, is directly connected with the power output interface, detects a voltage difference value of the power input interface and a voltage difference value of the power output interface, and controls the electronic lock to be locked when any voltage difference value exceeds a human body safety voltage so as to prohibit the high-voltage electrical control cabinet from being opened. When all the voltage difference values do not exceed the human body safety voltage, the electronic lock is controlled to be unlocked. According to the invention, when the high-voltage electrical control cabinet is opened, the main circuit breaker is effectively disconnected and the terminal voltage at the load is reduced to be below the safe voltage, so that the high-voltage electrical control cabinet is safely and reliably overhauled. The invention further discloses a high-voltage electrical control cabinet.
本发明公开了一种用于高压防护的电子锁控制电路，用于控制高压电气控制柜上电子锁开闭，高压电气控制柜具有电源输入接口和电源输出接口，总断路器控制电源输入接口和电源输出接口之间电回路的通断，电子锁控制电路的检测点通过总断路器接电源输入接口，直接接电源输出接口，检测电源输入接口的电压差值和电源输出接口的电压差值，在任一电压差值超出人体安全电压时控制电子锁锁死，以禁止高压电气控制柜打开，在所有电压差值未超出人体安全电压时控制电子锁打开。本发明可确保高压电气控制柜打开时，确保总断路器被有效断开且负载处端电压下降到安全电压以下，使得高压电气控制柜的检修安全可靠。本发明还公开了一种高压电气控制柜。
