Embodiment Construction

[0015] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0016] Please refer to the attached figure 1 As shown in Fig. 2, the present invention is a high-voltage switchgear, including a standard cabinet 1 with closed compartments arranged according to functional modules, a circuit breaker chamber 2 in the middle of the front side of the cabinet 1 and a voltage switch located at the lower front side of the cabinet 1. In the transformer room 3, the functional modules in each closed room are assembled on handcarts that can slide separately and be positioned on the working position or test position.

[0017] In the specific implementation, an interlock mechanism to prevent misoperation is set between the working position and the test position of the handcart. That is to say, when the high-voltage AC fast vacuum contactor 8 is in the closing position, the circuit breaker...

Abstract

The invention relates to a high-voltage switch cabinet, and particularly relates to a high-voltage switch cabinet. Sealed chambers are arranged in a standard cabinet body according to functional modules. Each sealed chamber comprises a circuit breaker chamber positioned at the middle part on the front side of the cabinet body, and a voltage transformer chamber positioned at the lower part on the front side of the cabinet body. The functional modules in the sealed chambers are assembled on a handcart capable of slipping on or being positioned on a work position or a test position; the circuit breaker handcart is formed by assembling a vacuum circuit breaker, a high-voltage current-limiting fuse and an upper chassis vehicle; and the circuit breaker handcart is equivalent to one functional module in a circuit breaker chamber; and a PT handcart, equivalent to a functional module in a voltage transformer chamber, is formed by assembling a voltage transformer, an over-voltage protector and a lower chassis vehicle. The switch equipment provided by the utility model has the advantages of simple structure, convenience in mounting and maintenance, low running cost, and capability of effectively improving the running safety of a power grid and the reliability of power supply, switching off the large short circuit current, and conveniently realizing the combination with other switch cabinets.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a high-voltage switch cabinet. Background technique [0002] Some of the electric control switch cabinets in the prior art have the characteristics of large volume, unreasonable internal structure layout, complicated operation and control, etc. The imported electric control switch cabinets have the disadvantage of high cost. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a high-voltage switchgear with simple structure, convenient installation and maintenance, and low operating cost, so as to improve the safety of power grid operation and the reliability of power supply. It can break a large short-circuit current, and can be combined with other switch cabinets conveniently. [0004] In order to achieve the above-mentioned purpose, the present invention adopts the following specific ...
