Normal-pressure air environment-friendly switch cabinet and outdoor switch box
The invention provides a normal-pressure air environment-friendly switch cabinet and an outdoor switch box, and belongs to the field of power distribution equipment. Dry air is used as insulating gas in a switch cabinet body, the pressure of the insulating gas is equal to one atmospheric pressure, and a grounding knife switch in the switch cabinet body is provided with an anti-misoperation locking device. An anti-misoperation electromagnet, a plurality of gears, a large reversing wheel, a small reversing wheel and other transmission components, a blocking piece, a key push plate and the like are arranged in a lock body of the anti-misoperation locking device, and the anti-misoperation electromagnet is electrically connected with the power supply wiring end of a power distribution box so that the anti-misoperation electromagnet can be powered on and started at the same time when the switch cabinet is powered on; and magnetic thrust is transmitted to the key push plate, the blocking piece and an anti-misoperation plug pin through a plurality of transmission parts, the key push plate is driven to push out a key, the blocking piece is pulled back to shield a key unlocking groove and drive the anti-misoperation plug pin to be inserted into the blocking piece, the blocking piece is fixed into the state of shielding the key unlocking groove, and safety accidents caused by misoperation are avoided. The normal-pressure air environment-friendly switch cabinet and the outdoor switch box have the beneficial effects of being good in safety performance, capable of preventing the key from being broken and environmentally friendly.
本发明提供一种常压空气环保型开关柜及户外开关箱，属于配电设备领域，开关柜主体内使用干燥空气作为绝缘气体且绝缘气体的气压等于一个大气压，开关柜主体内的接地刀闸设置有防误闭锁装置，防误闭锁装置的锁体内设置有防误电磁铁、若干齿轮和大小换向轮等传动部件、挡片和钥匙推板等，防误电磁铁与配电箱的电源接线端电性连接，以在开关柜通电时防误电磁铁同时通电启动，将磁推力通过若干传动部件传递到钥匙推板、挡片和防误插销，带动钥匙推板将钥匙推出，将挡片拉回遮挡钥匙解锁槽并驱动防唔插销插入挡片，使挡片固定在遮盖钥匙解锁槽的状态，避免误操作而造成安全事故，本发明具有安全性能好、防止钥匙被折断和环保的优点。
