Problems solved by technology
Under the existing equipment conditions, two testers need to lean into the middle cabinet at the same time. One person uses the transmission connecting plate on both sides to open the baffle, and the other operates the insulating caliper to lock the left and right driving connecting plates to keep it open. The use of this tool causes the hands and head of the operator to be very close to the live parts of the gate, which poses a safety hazard. In addition to the low safety factor, the operation is also quite difficult, which seriously affects the work efficiency of nuclear phase work.
In addition, the opening tools produced by switchgear manufacturers in the market are not universal due to the inconsistent specifications and sizes of different models of different manufacturers.

Embodiment Construction
[0007] The present invention will be further described below in conjunction with the accompanying drawings.
[0008] Such as figure 1 As shown, the stainless steel frame 1 is assembled by inserting and assembling four "L"-shaped modules, and the fixing of the four modules is realized by tightening the crimping bolts 5, and at the same time, the function of stretching and adjusting the length and width is realized. There are four handcart movement wheels 2, which are respectively arranged on the four sides of the bottom of the frame 1, the operating handle 4 is fixed on the rear side wall of the frame 1, and the connecting rod pressing plate 3 is two and is provided with an outward notch. They are respectively fixed on the left and right side board walls of the front part of the frame 1. There are two groups of locking structures, which are respectively fixed on the left and right sides of the frame 1 rear. Out of the depression bar 8 on the rear side wall of the frame 1, the...

The invention discloses a knife gate baffle opening device of a 10 kV centrally installed switchgear. The knife gate baffle opening device comprises a stainless steel frame with the adjustable length and width, four handcart moving wheels, two connecting rod laminating plates, an operation handle and two sets of locking structures. The four handcart moving wheels are arranged on the four edges of the bottom of the frame respectively. The operation handle is fixed to the back side plate wall of the frame. The two connecting rod laminating plates are provided with outward notches and are fixed to the left side plate wall and the right side plate wall of the front portion of the frame respectively. The two sets of locking structures are fixed to the left side plate wall and the right side plate wall of the back portion of the frame respectively. The knife gate baffle opening device is high in universality, the operation safety distance can be guaranteed for operators, and the working efficiency of nuclear phase tests is improved.
Description
technical field [0001] The invention relates to a gate baffle opening device. Background technique [0002] Due to the narrow space of the circuit breaker room of the central cabinet, the safety problem is prominent when the baffle plate of the front knife gate of the nuclear phase is opened. Under the existing equipment conditions, two testers need to lean into the middle cabinet at the same time. One person uses the transmission connecting plate on both sides to open the baffle, and the other operates the insulating caliper to lock the left and right driving connecting plates to keep it open. The use of this tool causes the hands and head of the operator to be very close to the live parts of the gate, which poses a safety hazard. In addition to the low safety factor, the operation is also quite difficult, which seriously affects the work efficiency of the nuclear phase. In addition, the opening tools produced by switchgear manufacturers in the market are not universal du...
