Problems solved by technology

The standardization coefficient of the product is very high. In terms of external dimensions, only high-voltage vacuum circuit breakers are divided into two specifications. According to different currents, only the plum blossom contacts are different, and it is difficult to distinguish different parameters in appearance.
[0004] During use and maintenance, once the operator withdraws the high-voltage vacuum circuit breaker from the armored removable switchgear and puts it in again, the parameters and nameplate must be carefully checked. A slight negligence will cause misuse and serious accidents

Embodiment Construction

[0027] The armored removable switchgear is composed of: the armored removable switchgear body 1 and the vacuum circuit breaker 2. The vacuum circuit breaker 2 is a removable part, such as Figure 1~3 shown.

[0028] Such as Figure 4 As shown, the armored removable switchgear body 1 and the matching chassis part of the vacuum circuit breaker 2 (not limited to this, other positions can also be divided in the same way) are divided into: application area, rated breaking current area, and rated current area , four areas of expansion area. The application area is identified according to the functional purpose; the rated breaking current area is identified according to the rated breaking current; the rated current area is identified according to the rated current; the extension area is reserved for other identifications, and the four areas constitute the overall identification combination.

[0029] Such as Figure 5 As shown, by installing logic blocks 3 in each area on the armor...

Abstract

The invention discloses a device and a method for error prevention of matching between an intelligent vacuum circuit breaker and armored movable switchgear. A logical block (3) is added on an armored movable switchgear body (1), a logical pin (4) is added on the vacuum circuit breaker (2), and therefore, one-to-one corresponding recognition is realized by means of mechanical forced interference to realize error prevention. Besides, a position sensor (5) is added to send signals to a control protector so that intelligentization is realized.

Description

technical field [0001] The invention belongs to the field of armored removable switchgear, and in particular relates to an anti-misidentification device and method for cooperation between a vacuum circuit breaker and a switchgear. Background technique [0002] In the 7.2kV ~ 40.5kV high-voltage field, the armored removable switchgear and the intelligent high-voltage vacuum circuit breaker have high reliability, high standardization coefficient, less maintenance and operating mechanisms, and the replacement of the circuit breaker is very simple, and the circuit breaker handcart is interchangeable. It has a series of advantages and is widely used in power distribution systems in various fields such as electric power industry, industrial and mining enterprises, railway transportation, etc. It is one of the main equipment that is indispensable for the development of electric power industry. [0003] Due to the technical progress of high-voltage components and armored removable s...
