Description

Technical Field

[0001] The utility model relates to the technical field of power controllers, in particular to a power controller which is easy to repair. Background Art

[0002] In the power system, air humidity has a great impact on the safe operation of electrical equipment. Only desiccant dehumidification or switch cabinet doors can be used for ventilation and heat dissipation dehumidification according to the situation. The dehumidification effect is poor and is greatly affected by the external environment. Once the humidity in the control cabinet is high, it will cause a short circuit in the line, which will cause immeasurable losses to the power company. At present, there are still a large number of electrical components that generate a lot of heat during use. Due to the use of electrical components, there are certain requirements for the temperature of the use environment. If the temperature inside the power control cabinet is high, there will be many problems in the use of electrical components, such as insufficient component accuracy and equipment failure, which will have a certain impact on the safety and temperature operation of the power system; Patent No. CN202022073907.4 discloses a smart power controller that is easy to repair. A set of symmetrical buckles are installed on the left and right sides of the bottom of the power controller housing, a set of symmetrical fixing blocks are installed on the bottom of the motor controller housing, and a set of symmetrical card slots are opened on the left and right sides of the top of the base. The card slots and the buckles are symmetrical with each other, so that the power controller housing can be fixed to the top of the base through the buckle connection in the card slot, and the top of the base is opened with a set of The fixing groove is called a fixing groove, the fixing groove and the fixing block are symmetrical to each other, the outer wall of the fixing block is provided with a threaded hole A, the outer wall of the base side is provided with a threaded hole B and the threaded hole B runs through the fixing groove, so that the fixing block is inserted into the fixing groove, the threaded hole A and the threaded hole B are symmetrical to each other and have the same size, so that the bolts are dragged through and fastened to the threaded holes A and B, so that the housing of the power controller and the base are fixed, which is convenient for later disassembly and maintenance; however, since the housing and the base of the power controller are not only fastened with bolts, but also installed and fixed by means of mutual clamping of the card block and the card slot, and when the card block and the card slot are disassembled from each other, the base needs to be lifted to push the card block clamped on the inside of the card slot and disassemble it. If the base is installed somewhere, it will be quite inconvenient to directly disassemble the shell for maintenance. For this reason, we propose an electric controller that is easy to maintain.
