Technical Field

The invention relates to the technical field of installation and fixation of controllers, in particular to a controller for a converter, which is convenient to install.

Background

The controller is a switching device capable of closing, carrying and opening/closing a current under a normal circuit condition and closing, carrying and opening/closing a current under an abnormal circuit condition within a prescribed time. The controller is divided into a high-voltage controller and a low-voltage controller according to the use range, the division of the high-voltage and low-voltage boundary lines is fuzzy, and the high-voltage and low-voltage boundary lines are generally called as high-voltage electric appliances with the voltage of more than 3 kV. The controller can be used for distributing electric energy, starting the asynchronous motor infrequently, protecting the power supply circuit and the motor, and automatically cutting off the circuit when serious overload or short circuit, undervoltage and other faults occur, and the function of the controller is equivalent to the combination of a fuse switch, an over-under-heat relay and the like. Furthermore, no parts need to be changed after breaking the fault current. At present, it has been widely used. Distribution of electricity is an extremely important link in the generation, transmission and use of electricity. The distribution system comprises a transformer and various high-low voltage electrical equipment, and the low-voltage controller is an electrical appliance with a large using amount. The controller generally comprises a contact system, an arc extinguishing system, an operating mechanism, a release, a shell and the like. When short circuit occurs, the magnetic field generated by large current (generally 10 to 12 times) overcomes the counterforce spring, the release pulls the operating mechanism to act, and the switch is controlled instantaneously. When the overload occurs, the current becomes large, the heating value becomes large, and the bimetallic strip deforms to a certain degree to push the mechanism to act (the larger the current is, the shorter the acting time is). In the existing electronic type, a mutual inductor is used for collecting the current of each phase, the current is compared with a set value, and a microprocessor sends out a signal when the current is abnormal, so that an electronic release drives an operating mechanism to act. The controller is used for switching off and switching on the load circuit and switching off the fault circuit, so that the accident is prevented from being expanded, and the safe operation is ensured. And the high-voltage controller is switched off at 1500V, and the 1500-power 2000 controller is provided with fixed electric arcs, and the electric arcs can be elongated to 2m and still continue to burn and are not extinguished. Therefore, arc extinction is a problem to be solved by the high-voltage controller.
