Abstract
The utility model relates to a 10-kV controllable combined-type over-voltage fuse protector which is characterized by comprising three controllable over-voltage fuse protectors; an A-phase operating mechanism, a B-phase operating mechanism and a C-phase operating mechanism are respectively provided with three controllable over-voltage fuse protectors; the A-phase operating mechanism and the C-phase operating mechanism are connected with the B-phase operating mechanism; and the B-phase operating mechanism is connected with a control box which is connected with a power supply. The 10-kV controllable combined-type over-voltage fuse protector can drive a rotating shaft mechanism by controlling a power-driven operating mechanism through a timing cut-off device, so that the dropping-type fuse protectors is cut off in a set time, an electric loop is cut off, the transformer stops running, the no-load loss of the transformer is reduced, and the purpose of energy conservation is achieved. Meanwhile, the 10-kV controllable combined-type over-voltage fuse protector has the functions of over-current protection and over-voltage protection for a 10-kV electric system.
Description
Technical field
The utility model relates to a kind of 10kV electric power system with having the fuse switch that overcurrent protection and overvoltage protection are regularly cut-off concurrently; it is a kind of combined electric appliance; generally install on 10kV distribution transformer high-pressure side or distribution wire service main road, as short circuit, overload protection and the overvoltage protection of transformer and circuit.
Background technology
The controllable type fuse rotating shaft mechanism design of in the past using is unreasonable, and the arm of force is longer, and it is bigger to cut-off strength, and fuse is not easy to cut-off, often the phenomenon that can not cut-off of appearance.Simultaneously, common controllable type fuse does not install lightning arrester additional, does not have over-voltage protection function.
Summary of the invention
The purpose of this utility model provides a kind of Contrable combination type overvoltage fuse that reduces the no-load loss of transformer and over-voltage protection function is arranged.
In order to achieve the above object, the technical solution of the utility model has provided a kind of 10kV Contrable combination type overvoltage fuse, it is characterized in that, comprise three controlled overvoltage fuses, A phase operating mechanism, B phase operating mechanism and C phase operating mechanism are respectively equipped with three controlled overvoltage fuses, A phase operating mechanism and C operating mechanism mutually connect B phase operating mechanism, and B phase operating mechanism connects control box, and control box links to each other with power supply.
Further, described controlled overvoltage fuse comprises fuse switch, upper end and lower end at fuse switch are respectively equipped with upper connecting terminal and lower connecting terminal, the lower end of fuse switch links to each other with lightning arrester by rotating shaft mechanism, upper end at lightning arrester is provided with mounting panel, and A phase operating mechanism, B phase operating mechanism or C phase operating mechanism are located on the mounting panel.
The utility model is that lightning arrester and insulator are contained on the device that can freely fall, and realizes freely cut-offfing.
The utility model can be controlled motor-operating mechanism by the timing breaking device, thereby drives rotating shaft mechanism, and fuse switch is cut-off at setting-up time, and power circuit disconnects, and transformer is out of service, reduces the no-load loss of transformer, reaches purpose of energy saving.Have 10kV electric power system overcurrent protection and over-voltage protection function simultaneously concurrently.
