Embodiment

[0058] Due to the actual needs of production, according to the dispatching requirements, a 35kV standby 750 line in a substation is changed from operation to switch and line maintenance. Below will adopt the inventive method to install the five anti-locks additionally under the situation of switchgear, change the 35kV stand-by 750 line from operation into switch and line maintenance.

[0059] Figure 7 It is a schematic diagram of a 35kV standby 750 switchgear with five anti-locks, which includes the front door of the 35kV standby 750 switchgear, the swing hole of the trolley, the grounding knife of the standby 750 line, the rear upper cabinet door, and the rear lower cabinet door Install five anti-locks with anti-misoperation function.

[0060] First of all, the operating personnel issue tickets according to the dispatching order, and the operation ticket for the 35kV standby 750 line to be changed from operation to line maintenance is as follows:

[0061] 1) Pull the stand...

Abstract

The invention provides a microcomputer anti-misoperation locking system and method for a high-voltage switch cabinet of a substation. The high-voltage switch cabinet of the substation comprises a main transformer switch cabinet, a main transformer switch blade cabinet, a capacitor switch cabinet, a grounding variable switch cabinet, a female branch switch cabinet, a female branch switch blade cabinet, a bus voltage transformer cabinet and a line switch cabinet. According to the microcomputer anti-misoperation locking system for the high-voltage switch cabinet, five-prevention locks with an anti-misoperation locking function are added to a front cabinet door, a rear cabinet door, a trolley shaking hole and a grounding switch blade of the line switch cabinet respectively; and the five-prevention locks with the anti-misoperation locking function are added to the front cabinet doors, the rear cabinet doors and the trolley shaking holes of the main transformer switch cabinet, the main transformer switch blade cabinet, the capacitor switch cabinet, the grounding variable switch cabinet, the female branch switch cabinet, the female branch switch blade cabinet and the bus voltage transformer cabinet respectively. According to the method, operating personnel make out an invoice according to a dispatching command; the drawn operation invoice is checked and signed by a shift supervisor and a deputy shift supervisor; and switching operation of changing a stand-by line of the high-voltage switch cabinet into switch and line maintenance from operation can be carried out.

Description

technical field [0001] The invention relates to a microcomputer anti-misoperation locking system and method for a high-voltage switchgear in a substation, belonging to the field of electric equipment tools. technical background [0002] In modern society, electricity plays an extremely important role in the national economy, national security, and people's daily life. As an important electrical equipment in the power system, high-voltage switchgear is generally used in 10-35kV substation equipment. Focusing on the transmission and protection control of electric energy, it provides users with high-quality electric energy. With the rapid development of substation automation technology and the increasing requirements for power supply reliability, the role of switchgear in substations is also more prominent. Therefore, how to ensure the safe and reliable operation of the high-voltage switchgear in the substation has become an important task in the operation and maintenance of p...
