Description

High-voltage switch cabinet with openable valve Technical Field The utility model relates to the technical field of high-voltage switch cabinets, in particular to a high-voltage switch cabinet with an openable valve. Background In the technical field of urban power distribution, the middle-mounted high-voltage switch cabinet has the advantages of compact structure and high operation reliability, and is widely applied to power systems. However, when operations such as high-voltage cabinet operation monitoring, defect elimination, overhaul and maintenance are performed, the charged part is hidden in the valve, so that the operation safety requirement on the charged part is extremely high. Existing high voltage switchgear service systems are typically configured with a ground test cart. The inner wall of the handcart room of the high-voltage cabinet is provided with an upper row of static contacts and a lower row of static contacts, and after the circuit breaker handcart exits from the working position, the two rows of static contact holes are covered and protected by two baffle type valves. The two valves are respectively controlled by the valve mechanisms at the left side and the right side in the cabinet through the upper valve connecting rod mechanism and the lower valve connecting rod mechanism, when the upper valve connecting rod mechanism moves downwards, the lower valve is driven to synchronously pull downwards to expose the lower static contact hole, and when the lower valve connecting rod mechanism moves upwards, the upper valve is driven to synchronously move upwards to expose the upper static contact hole. The existing maintenance operation flow is that firstly the valve structure is pushed away by the electricity checking handcart, the electricity checking operation is implemented by the electricity checking rod, the electricity checking handcart is withdrawn after no voltage is confirmed, and then the grounding handcart is used for grounding the static contact, so that the maintenance safety is ensured. However, the electricity inspection handcart only has a valve opening function, so that two independent trolleys are required to be equipped for single maintenance, and each handcart is required to be provided with a chassis special for a circuit breaker, so that the manufacturing cost of equipment is high, the whole structure of the handcart is heavy, and the problems of difficult carrying, complicated vehicle changing process and the like exist in actual operation, so that the maintenance operation efficiency and convenience are seriously affected. In view of this, the present inventors have specifically devised a high-voltage switchgear with an openable shutter, which is produced thereby.
