Novel high pressure is aerifyd cabinet lower door and is linked structure firmly

Technical Field

The utility model relates to an aerify cabinet technical field, concretely relates to novel high pressure aerifys cabinet lower door and links structure firmly.

Background

According to the requirements in GB 3906-2006 3.6-40.5 kV alternating current metal-enclosed switchgear and control equipment, all high-voltage equipment needs to have the requirement of five prevention, namely 1, a cabinet door can be opened only in a switch grounding state; 2. the grounding switch can be disconnected only when the cabinet door is closed; 3. only when the grounding switch is in the opening position, the closing operation of the switch can be carried out; 4. the closing operation of the earthing switch can be performed only when the switch is in the open position. 5. When the switch is at the closing or opening position, the lower door can not be opened. To achieve this, the plant needs to install an additional set of lower door interlocking device. The existing interlocking device adopts a flexible connection mode, the interlocking is realized by utilizing the locking buckles of the hose and the lower door and the separation blades at the opening and closing positions, when the switch is operated in a closing and opening mode, the positions of the separation blades at the opening and closing positions are different, and the locking buckles of the lower door are pulled by utilizing the transformation ratio of the positions through the hose, so that the requirement of five prevention is realized. Because the hose among the flexible coupling needs the scene to be cuted, the size of hose can have the error, and work efficiency is low, and if the position installation of separation blade is inaccurate, can cause the displacement not enough, the chain unstable problem of lower door.
