Problems solved by technology
During the non-stop operation of the distribution network, there are many circuit breakers on the pole. Before the operation, insulation and shielding measures are required. At present, insulation blankets are mainly used for shielding. The shielding parts are the upper pile head, the lower pile head and the knife switch of the pole-mounted circuit breaker. In order to complete all the shielding work, more than 9 insulating blankets are required. The process is very cumbersome, the workload is heavy, and there are safety risks in the shielding process.

Embodiment Construction
[0027] The present invention will be further described in conjunction with the following application scenarios.
[0028] see Figure 1-3 , a combined pole-mounted circuit breaker insulation shielding cover, which includes a shielding cover main body 1 made of insulating materials, an opening and closing baffle 2, a side baffle 3, a top baffle 4, and a handle 5, in
[0029] The main body 1 of the shielding cover is in the shape of a regular cuboid, and the front is made of a whole piece of insulating material, with openings on both sides;
[0030] The opening and closing baffle 2 is a movable insulating baffle installed on the side of the shielding cover main body 1. When the shielding cover is installed, the opening and closing baffle is opened; after the installation is completed, the opening and closing baffle is closed. Ensure that the shielding cover is firmly shielded during the circuit breaker on the shielding column;
[0031] The top baffle plate 4 is located on the ...

The invention provides an insulating shielding cover of a combined type pole-mounted circuitbreaker. The shielding cover comprises a shielding cover main body which is made by an insulating material, an open and close baffle, side edge baffles, a top baffle, and a handle. The shielding cover main body is in a regular rectangular shape, and a front surface is made of an integrated insulating material, and two sides are open. The open and close baffle is an integrated moveable insulating baffle and is arranged on a side surface of the shielding cover main body, and is used to ensure firm shielding of the shielding cover in a process of shielding the pole-mounted circuitbreaker. The top baffle is on the top of the other side surface of the shielding cover main body, and is used to prevent cut-off or switching-on of a knife switch. The handle is arranged on the upper part of the shielding cover main body, and is used for an operator to hold the insulating shielding cover. The insulating shielding cover can satisfy requirement of completely and effectively shielding a pole-mounted circuitbreaker, and is advantaged by convenient, fast, and safe operation.
Description
technical field [0001] The invention relates to an insulating shield safety appliance, in particular to a combined pole-mounted circuit breaker insulating shield. Background technique [0002] With the increasingly higher requirements for the reliability of power supply in urban distribution networks, uninterrupted power supply operations have gradually become an important method for various maintenance work and emergency repair work. Insulation shielding is an important means to ensure the safety of people and equipment in uninterrupted operation, and it is also a key link that affects the efficiency of uninterrupted operation. During the non-stop operation of the distribution network, there are many circuit breakers on the pole. Before the operation, insulation and shielding measures are required. At present, insulating blankets are mainly used for shielding. The shielding parts are the upper pile head, lower pile head and knife switch of the pole-mounted circuit breaker. ...
