Safety locking device of 10 kV ring main unit and locking control system

Abstract

The invention provides a safety locking device of a 10 kV ring main unit and a locking control system. The safety locking device at least comprises the ring main unit, a high-voltage sensor is arranged in the ring main unit, the ring main unit is at least provided with a grounding switch operating mechanism, the high-voltage sensor is connected with a GYN2 high-voltage live part verification display device, a GYNS mechanical padlock is installed on the grounding switch operating mechanism through a locking mechanism, and the GYN2 high-voltage live part verification display device and the GYNS mechanical padlock are provided with a computer key which can conduct live part verification on the GYN2 high-voltage live part verification display device and can unlock and lock the GYNS mechanical padlock. The locking control system comprises an industrial control host with background management software, the industrial control host is connected with the computer key through a transmission adapter, locking data, set on the industrial control host and corresponding to one another, of a high-voltage live display device and a locking device are transmitted to the computer key through the transmission adapter, and the safety locking device is controlled through the computer key. The safety locking device of the 10 kV ring main unit and the locking control system have the advantages of being convenient to construct, safe, reliable, reasonable in structure, capable of perfecting the anti-misoperation locking function of the ring main unit and the like.

Description

technical field [0001] The invention relates to a safety locking device and a locking management and control system of a 10kV ring main unit, and belongs to the technical field of power pipe network safety assurance. Background technique [0002] With the continuous increase of the city, the city's cleanliness and beautification requirements continue to increase, and the urban power cable network plays a pivotal role. At present, more than 90% of the general urban power cable network are ring network cabinets, and the ring network cabinets all adopt the "hand in hand" wiring mode. This mode presents a serious safety hazard at the normal disconnection switch - that is, the switch is in the heat. In the standby state, the grounding switch on the line side loses the lockout. For a long time, the distribution network has been frequently operated, and the main guarantee of safety is the check of the on-site switch of the operating personnel and the constraints of the operation t...

AI Technical Summary

Problems solved by technology

The locking is reliable, and it is the most basic form of electrical locking, but it needs to connect a large number of secondary cables, the wiring method is more complicated, and the operation and maintenance are more difficult

Its functions are also relatively few. Generally, it can only prevent the misoperation of switches, spacers and floor knives, but it can't do anything about mistakenly entering the charged interval, the connection (removal) of the ground wire, etc.
