Embodiment Construction

[0029] see figure 1 , figure 2 , with reference to Figure 6 , The safety device for the opening and closing of the withdrawable circuit breaker isolation baffle of the present invention is installed in the drawer seat chassis 1 of the circuit breaker, including four isolation baffles 2, a guide plate 3 and two springs 4.

[0030] Cooperate see Figure 4 , the structures of the four isolation baffles 2 in the present invention are the same, all of which are rectangular plate structures. A plurality of windows 21 are evenly spaced in the middle of each isolation baffle, and the middle part of one side extends outwards with two protrusions. Block 22,23, form a square guide groove 24 between two projections, the width of this square guide groove 24 and the width of the guide rail 31 on the guide plate 3 are adapted, and each isolation baffle plate 2 is by its square guide groove 24 and The corresponding guide rails 31 on the guide plate 3 are fitted and movably connected. Am...

Abstract

A safety device for opening and closing isolating baffles of a withdrawable circuit breaker is arranged in a base support of a drawer seat of the circuit breaker and comprises four isolating baffles, a guide plate and two springs. Two of the four isolating baffles are arranged on a horizontal slide pre-arranged on the upper portion of the base support, and the other two baffles are arranged on a horizontal slide pre-arranged on a lower portion of the base support. The guide plate is inserted on a slot hole pre-arranged on the base support. The upper surface and the lower surface of the guide plate are respectively provided with two guide rails, and the inner end of the guide plate is provided with two guide rods. The two guide rails arranged on the upper surface of the guide plate are respectively in embedded connection with the two isolating baffles arranged on the upper portion of the base support, and the two guide rails arranged on the lower surface of the guide plate are respectively in embedded connection with the two isolating baffles arranged on the lower portion of the base support. The two springs are respectively sleeved on the two guide rods arranged on the guide plate. The safety device has the advantages of being compact in structure, reliable in opening and closing of the isolating baffles of the drawer seat of the circuit breaker, synchronous and stable, convenient in assembly and utilization and the like.
