Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0026] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; the specific way that one element is fixedly connected to another element can be realized through existing technologies, and will not be discussed here. To repeat it agai...

Abstract

The invention discloses a dynamo van inlet box. The dynamo van inlet box comprises a box body, a first power connection mechanism and a second power connection mechanism, wherein the box body is provided with a mounting cavity and a mounting plate; the first power connection mechanism comprises a plug assembly and a first power connection circuit; the plug assembly is arranged on the mounting plate; the first power connection circuit is arranged in the mounting cavity and is electrically connected with the plug assembly; the second power connection mechanism comprises a connector assembly and a second power connection circuit; the connector assembly is mounted on the inner wall of the mounting cavity; the second power connection circuit is arranged in the mounting cavity and is electrically connected with the joint assembly; and after the first power connection circuit is in parallel connection with the second power connection circuit, a power supply circuit which is electrically connected with an alternating current cabinet is formed. Therefore, the inlet box can be alternately connected with two or more than two dynamo vans in a seamless manner to be connected with power, power supply of the inlet box is reliable when an alternating current system for a station (the alternating current cabinet) is in a power failure state for a long time, and economic loss caused by time consumption due to the fact that a cable is plugged again is avoided.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a connection box of a power generation vehicle. Background technique [0002] At present, thunderstorms and typhoons that often occur in southern my country have brought great challenges to the safe operation of power systems. When a large amount of lightning current shields the power equipment or a large number of floating objects hang on the power equipment, it may cause a power outage of the substation equipment or even a loss of voltage in the entire substation. According to statistical analysis, after the whole substation loses voltage, the connection time of the standby generator car power supply is generally longer, about 3 to 5 hours. [0003] When the station voltage loss occurs in the substation, the emergency generator car is usually used to connect to the 380V station AC system to temporarily solve the power problem. However, the existi...
