Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a pole-mounted circuit breaker with a slide rail installation mechanism. Background Art

[0002] Pole-mounted circuit breakers refer to circuit breakers installed and operated on electric poles. The theoretical research level and manufacturing technology of various circuit breakers have made great progress. Vacuum circuit breakers are not only limited to medium-voltage power grids, but are developing towards high voltage and large capacity. Sulfur hexafluoride circuit breakers have many advantages, such as strong breaking capacity, many continuous breaking times, frequent operation, low operating noise, no fire hazard, etc., and are a good oil-free equipment.

[0003] In the prior art, a Chinese patent with publication number CN217134300U discloses a pole-mounted circuit breaker with a slide rail mounting mechanism, which is used to solve the problems existing in the prior art, and includes two groups of left and right connection platforms and a circuit breaker body, and the surface of one side of the connection platform is fixedly connected with an adjustment mechanism for adjusting the spacing between the two groups of left and right connection platforms. The staff pulls out the clamping fixing mechanism in the clamping frame, and pushes the insulating plate to make the fixed base plate slide up and down in the adjustment slide groove through the slider, thereby adjusting the height of the circuit breaker body, and then clamps it into the clamping frame corresponding to the height of the circuit breaker body through the clamping fixing mechanism, so that the staff can perform construction operations on the circuit breaker body. The above method realizes the lifting and lowering of the circuit breaker, avoids the staff from disassembling the circuit breaker, and avoids the consumption of a lot of manpower and material resources, and also avoids damage to the equipment, and prevents possible casualties.
