Problems solved by technology

[0002] In the prior art, most of the DC traction feeder cabinets are made of iron and other metals. Due to the good ductility of metal, the DC traction feeder cabinets are easily deformed due to external impact during transportation, which makes the gap between the internal electronic components contact is affected, resulting in affecting the working stability of the DC traction feeder cabinet
In addition, the interchangeability of the existing DC traction feeder cabinets is poor. When a DC traction feeder cabinet fails, it cannot overcome the impact of its failure by exchanging it with other DC traction feeder cabinets

Abstract

The present invention relates to a modularization direct current traction feeder cabinet. The cabinet comprises a cabinet body, the front side of the cabinet body is provided with a cabinet door capable of opening or closing, the interior of the cabinet body is divided into a busbar chamber and a breaker chamber, the breaker chamber is located at the front side of the busbar chamber, the breaker chamber is internally provided with a breaker distribution cabinet unit and a breaker handcart, the breaker distribution cabinet unit is fixedly arranged at the inner bottom surface of the breaker chamber, the breaker handcart is arranged in the breaker distribution cabinet unit, and when the cabinet door is opened, the breaker handcart can be pulled out or pushed into the breaker distribution cabinet unit from the opening of the cabinet door; and the upper portion of the breaker handcart is provided with the breaker, when the breaker handcart is pushed into the breaker distribution cabinet unit, the breaker is contacted with and electrically connected with the copper bar in the busbar chamber. The structure is concise, and the breaker unit portion with high matching requirement is subjected to modularization design to improve the matching precision of the breaker contact so as to greatly improve the electrical stability performances of products and realize the complete interchangeability of the breaker distribution cabinet.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a modular DC traction feeder cabinet. Background technique [0002] In the prior art, most of the DC traction feeder cabinets are made of iron and other metals. Due to the good ductility of metal, the DC traction feeder cabinets are easily deformed due to external impact during transportation, which makes the gap between the internal electronic components The contact is affected, resulting in affecting the working stability of the DC traction feeder cabinet. In addition, the interchangeability of the existing DC traction feeder cabinets is poor. When a DC traction feeder cabinet fails, it cannot overcome the impact of the failure by exchanging it with other DC traction feeder cabinets. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a modular DC traction feeder cabinet for the above-mentioned defi...
