[0002] The high voltage cabinet is an important component of the power system. The static contact of the middle high voltage cabinet is installed in the contact box of the switch cabinet, and six are installed in one switch cabinet, two for each of the three phases ABC. When the bus is in operation, the upper static contact is in a charged state. When the circuit breaker is slowly shaken from the test position to the working position, the top rod on both sides of the circuit breaker pushes the two crank arms of the movable baffle, and the crank arms drive the connecting rod mechanism to open the upper and lower movable baffles. The moving contact of the circuit breaker connects the static contact, and the electrical circuit is connected. When the power is off, the circuit breaker is slowly shaken out, the top rod on both sides of the circuit breaker is also withdrawn, and the upper and lower movable baffles are lowered to close the contact box due to gravity, thereby ensuring the safety of the maintenance personnel.
