[0002] The distribution box is a control cabinet that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements of the normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment. Since there are many electrical equipment installed inside the distribution box, and the electrical equipment will generate heat when it runs for a long time or under high load, if the internal temperature is too high, it may accelerate the aging of the electrical equipment or cause a short circuit. Therefore, it is necessary to dissipate heat. Although some distribution boxes have heat dissipation devices, the heat dissipation devices are usually installed with screws, that is, the screws are tightened one by one. After the heat dissipation device is fixed, the position cannot be adjusted, and the heat dissipation cannot be carried out in a targeted manner. For this reason, we propose a distribution box with monitoring function. Utility Model Content

The distribution box with monitoring function places the heat sink between two fixed blocks, and uses the fixed blocks to squeeze the limit rod so that the limit rod moves toward the inner cavity of the heat sink, drives the baffle to move, and stretches the contraction spring at the same time. When the limit rod reaches the position of the limit slot, the contraction of the contraction spring is used to make one end of the limit rod enter the inner cavity of the limit slot to complete the installation. When disassembling, the limit rod is pushed by the movable block to move the limit rod out of the inner cavity of the limit slot. The operation is convenient. A temperature sensor is installed inside the distribution box body, and the temperature inside the distribution box body is monitored by the temperature sensor.
