Problems solved by technology

If there are users at the back end of the crossing cable, the live work cannot be carried out, which not only prolongs the power restoration time of the crossing cable, but also needs to perform power outage lapping on the repaired cable, resulting in a power outage for users and reducing the reliability at the same time.

Embodiment Construction

[0020] In order to better understand the technical solution of the present invention, the following will be described in detail through specific examples:

[0021] see figure 1 with figure 2 , a pole-mounted circuit breaker of the present invention includes a circuit breaker 1 and a circuit breaker base 2 .

[0022] The base 2 is composed of a hoop 21 and a triangular support 22 . The base 2 is connected to the pole through a hoop 21 , and the triangular support 22 supports the circuit breaker 1 .

[0023] The circuit breaker 1 includes a box body 11 , an arc extinguishing chamber, three-phase contacts and an operating handle 12 , an upper connecting contact 13 and a lower connecting contact 14 .

[0024] The arc extinguishing chamber is set in the box. It is a linear gas interrupting chamber with three-phase integrated linkage. The arc extinguishing chamber has a transparent cover. When the moving contact is moving, it uses the cooperation with the cover to generate the a...

Abstract

The invention discloses a pole-mounted circuit breaker, which comprises a circuit breaker and a circuit breaker base, wherein the base is fixedly connected with an electric pole, and the circuit breaker is connected to the base through a firmware; the circuit breaker comprises a box body, an arc extinguish chamber, a three-phase contact, an operating handle, an upper connecting contact and a lower connecting contact, the arc extinguish chamber is arranged in the box body, the operating handle is arranged on the side face of the box body and connected with the three-phase contact through a spring mechanism, the three-phase contact is located in the arc extinguish chamber, the spring mechanism is sealed in an air chamber of the arc extinguishing chamber, the arc extinguishing chamber is a transparent housing, and observation windows used for observing the movement range of the three-phase contact are formed in the bottom and the side face of the box body. The 10kv wire is connected with the upper contact head, the upper contact head is connected with the lower contact head through a lead in the arc extinguishing chamber, and the lower contact head is connected with the lower lead. The crossing cable can be rapidly isolated, and the fault processing power failure time is shortened; after cable faults are repaired, power supply can be recovered quickly.

Description

technical field [0001] The invention relates to a pole-mounted circuit breaker used in the field of electric power engineering. Background technique [0002] As the most important part of the lean operation and maintenance of distribution network equipment and the fault voltage drop project, the full insulation transformation project is of great significance to improve the ability of the network frame to prevent external force faults. At present, the electric power industry is combining various engineering projects to accelerate the full insulation transformation of distribution lines by means of non-stop operation to reduce tripping failures caused by external factors such as foreign objects and small animals. At present, there are a large number of crossing cables in the urban area, and the existing crossing cable boarding method is that the traditional outgoing cable is directly connected with the 10kv conductor wire through connecting fittings. When the crossover cable ...
