Abstract
The invention pertains to the technical field of power network control, in particular to a control system for the disconnection of a 10kV power network terminal. The technical proposal of the control system for the disconnection of the 10kV power network terminal comprises the 10kV power network terminal, a distribution transformer, a falling safety brake connected between the 10kV power network terminal and the distribution transformer, a low-voltage line for the output of the distribution transformer, a line connected with load and a switch mechanism connected between the low-voltage line and the line connected with the load; the upper end of the falling safety brake is provided with a spring sheet and a tripping mechanism which are matched with the end part of a brake tube; the tripping mechanism is connected with the end part of a leverage provided with a fulcrum; the other end of the leverage is controlled by an alternating current contactor; a control mechanism is arranged between the alternating current contactor and the low-voltage line for the output of the distribution transformer. The system can solve the problem that thousands of seasonal or temporary client ends are likely to cause a distribution transformer connected under a high-voltage end to be in the state of no-load operation for a long time; the system also has the advantages of simple line control and convenient maintenance.
