Distribution network automatic control device for power grid dispatching

Abstract

The invention belongs to the field of automatic disconnecting switches. The distribution network automatic control device for power grid dispatching comprises a base, insulators A, wiring boards, an inverted T contact, a knife switch mechanism, insulators B, a transmission shaft and a stepping motor; the two vertical insulators A are symmetrically installed on the base; and the wiring boards withwiring holes are installed at the upper ends of the insulators A respectively. According to the distribution network automatic control device for power grid dispatching of the invention, two L-shapedplates A are matched with two external threads with opposite rotating directions at two ends of a pin A respectively; and when two swing plates swing upwards simultaneously along with the L-shaped plates A hinged to the swing plates, the two swing plates of which the middle portions hinged in a crossed mode swing oppositely around a hinged point between the two swing plates, so that two conductiveplates release the clamping of the inverted T-shaped contact and are separated from each other, and therefore, a disconnecting switch is turned on. In a working process, the stepping motor only overcomes the obstruction of a plate spring B with a very small elastic coefficient and breaks a balance-approximating state between the plate spring B and the stepping motor, and the stepping motor consumes less energy and has a better energy-saving effect.

Description

technical field [0001] The invention belongs to the field of automatic isolation switches, in particular to a distribution network automation control device used for grid dispatching. Background technique [0002] Now the pace of urbanization is getting faster and faster, and the development of cities is getting faster and faster, and the consumption of electric energy is getting larger and larger; The distribution network automation equipment is proposed. The distribution network automation equipment for power grid dispatching includes a large number of automatic isolation switches. As an indispensable switch component in high-voltage lines, the electric drive module in the automatic isolation switch is connected to the PLC, and the isolation switch can be realized through remote control. On and off; while the automatic isolation switch in the existing technology is more difficult to close or separate the knife when the control system controls it to open or close, it requi...

Problems solved by technology

The distribution network automation equipment for power grid dispatching includes a large number of automatic isolating switches, which are essential switching components in high-voltage lines. The electric drive module in the automatic isolating switch is connected to PLC, and the isolating switch can be controlled by remote control. On and off; while the automatic isolating switch in the existing technology is controlled by the control system to open or close, it is difficult to close or separate the switch knife, and it needs a relatively high-power electric drive to complete; on the one hand, the cost is higher ; On the other hand, the opening and closing of the switch knife consumes a lot of power. For thousands of automatic isolating switches, the total energy consumption is considerable; how to effectively reduce the energy consumption of the automatic isolating switch is the basic One of the important topics studied by technical personnel in the field
