Description

Technical Field

[0001] The utility model relates to the technical field of fused column mounted circuit breakers, in particular to a primary and secondary fused column mounted circuit breaker with a heat insulation function. Background Art

[0002] Pole-mounted circuit breakers refer to circuit breakers installed and operated on electric poles. The power research level and manufacturing technology of various circuit breakers have made great progress. Pole-mounted circuit breakers are not limited to medium-voltage power grids, such as strong breaking capacity, many continuous breaking times, frequent operation, low operating noise, and no fire hazard.

[0003] The prior art discloses a primary and secondary fusion column-mounted circuit breaker with heat insulation function, which is announced as CN218631849U, and includes a base, a column mechanism is arranged above the base, a mounting support mechanism is arranged above the column mechanism, and a circuit breaker heat insulation mechanism is arranged above the mounting support mechanism. By setting a lifting structure, the circuit breaker body is lifted and lowered, and the concave grooves and rainwater drainage holes arranged on the mounting bearing plate can effectively prevent water accumulation on the mounting bearing plate caused by rain, thereby preventing the bottom of the heat insulation box from being immersed in water for a long time. The cold water in the cooling water tank is sent into the conduit through the outlet pipe through the water pump, and then flows back to the cooling water tank through the inlet pipe, so that the cold water in the conduit takes away the heat in the circuit breaker. The curved conduit increases the heat absorption contact area of ​​the conduit and prolongs the time for the cold water to circulate in the conduit. The circuit breaker can cool down the inside and has a heat insulation function, which prevents the circuit breaker from overheating and causing the circuit to fail to work.

[0004] The above-mentioned primary and secondary fusion column-mounted circuit breaker is provided with a curved conduit to increase the heat absorption contact area of ​​the conduit and at the same time prolong the time for cold water to circulate in the conduit, thereby increasing the range and time for cold water to cool the circuit breaker. However, when the above-mentioned device is attached to the circuit breaker for heat dissipation, only the contact part can dissipate heat, and the contact part cannot be raised or lowered, resulting in a small heat dissipation area and low heat dissipation efficiency. The effect during use is not good, and this needs to be improved. Utility Model Content
