Problems solved by technology

However, the control cable of the live operation terminal is likely to cause accidental tripping, affect the normal power consumption of customers, and increase the risk of customer complaints; at the same time, for multiple control loops, when the cables are restored, it is easy to cause the control loops to be connected in series, causing accidents; When handling the control cable connector, it is easy to cause the operation and maintenance personnel to get an electric shock, threatening the personal safety of the collection operation and maintenance

Abstract

The invention discloses a control cable opening and closing device of a high-voltage load control terminal and an opening and closing method. The control cable opening and closing device comprises an insulating support base, wherein a wiring terminal block is arranged at each of two sides of the insulating support base; each wiring terminal block is provided with a plurality of wiring terminals; the wiring terminals at one side are correspondingly connected with moving contacts through insulated guide wires; the wiring terminals at the other side are correspondingly connected with fixed contacts through the insulated guide wires; all moving contacts are arranged on a same shaft; the shaft is arranged on a sliding rail in a sliding manner; and each wiring terminal is also connected with a control cable. The control cable opening and closing device is simple in structure, convenient to install, safe in operation and long in service lifetime; and the technical problem in an existing terminal replacement process is effectively solved. By the control cable opening and closing device, tripping power outage of a measuring cabinet since that an exposed joint of the control cable at a terminal side is accidentally touched by replacing the terminal is avoided; and meanwhile, an electric shock since the operation and maintenance staff accidentally touches a + / -100V control power supply is also avoided.

Description

technical field [0001] The invention relates to an opening and closing device and an opening and closing method for a control cable of a high-voltage negative control terminal. Background technique [0002] At present, all newly installed high-voltage substation users have implemented the power purchase control function, using load control terminals to control users' electricity consumption, and implementing the "prepaid" electricity consumption mode, which has effectively improved the efficiency of electricity charge recovery for high-voltage substation users, and is a "full coverage, all-round The full implementation of collection and full fee control has laid a solid foundation. The normal operation of the terminal is an important guarantee for the realization of the fee control and collection functions. At this stage, it is in a period of rapid development of high-voltage power purchase control, and the operation and maintenance of the negative control terminal needs to ...
