The beneficial effects of the utility model：
1. the utility model is improved to existing High-Voltage Electrical Appliances disconnecting switch, small volume is simple in construction, moreover, this
Utility model is realized using backrush spring and closed a floodgate, when moving knife arm is contacted with upper connecting terminal and lower connecting terminal, due to backrush bullet
The elastic force effect of spring, moving knife arm is not easily disconnected from upper connecting terminal and lower connecting terminal, it is ensured that in combined floodgate rear dynamic knife arm and upper wiring
Terminal and lower connecting terminal are contacted well all the time, without bolt fastening, will not be easy to because brake hop phenomenon is occurred by ectocine
Separating brake, further, since using backrush spring automatic closing, therefore increase latch carries out self-locking, latch can not only avoid isolation
Switch is influenceed and automatic closing in gate-dividing state by external shock and backrush spring force, is eliminated safe hidden trouble, while can
Moving knife arm is limited after combined floodgate to rotate, and coordinates the position of the elastic force effect limitation moving knife arm of backrush spring, it is to avoid brake hop.
