The switch car of this kind of mobile substation includes: a circuit breaker; a lightning arrester; and the circuit breaker and the lightning arrester are arranged on the mobile platform, one end of the circuit breaker is close to the lightning arrester, and the other end of the circuit breaker is connected with a wiring sleeve and a cable plug head. By arranging the wiring sleeve and the cable plug head for the circuit breaker, the switch car of the mobile substation can be connected with a power grid more flexibly in different modes.
According to an aspect of the utility model, the moving platform is a semitrailer.
According to the utility model discloses a further aspect, the circuit breaker with the arrester contains in a high-voltage combined electrical apparatus, high-voltage combined electrical apparatus is located on the semitrailer. The adoption of the high-voltage combined electrical apparatus is beneficial to obtaining a more compact structure.
According to the utility model discloses a still another aspect, the semitrailer has a height adjusting device. The height adjusting device is beneficial to the opening and closing of the vehicle to pass through some road sections with limited height.
According to another aspect of the present invention, the cable plug is a high voltage cable plug head.
According to the utility model discloses a still another aspect, the last sulfur hexafluoride gas fills gassing device of still installing of moving platform. The sulfur hexafluoride gas charging and discharging device can rapidly charge the breaker or the switch before the sulfur hexafluoride gas charging and discharging device is put into operation.
According to a further aspect of the invention, the switch car has an online detection device. The online detection equipment can reduce the time of field experiments.
The above features, technical features, advantages and modes of realisation of the present invention will be further described in the following detailed description of preferred embodiments, which is to be read in conjunction with the accompanying drawings.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or structurally similar elements that perform the same function, and elements having the same structure or function are depicted schematically, or are identified. For the sake of simplicity, only the parts relevant to the present invention are schematically shown in the drawings, and they do not represent the actual structure as a product. "connected" herein means directly connected or connected through a third party.
As shown in fig. 1 and 2, the switchyard for a mobile substation includes a circuit breaker 22, an arrester 26, and a mobile platform 21, wherein the circuit breaker 22 and the arrester 26 are mounted on the mobile platform 21. The mobile platform 21 may be a semi-trailer as shown in fig. 1 and 2. One end of the circuit breaker 22 is arranged close to the lightning conductor 26, while the other end is connected to a connection bushing 24 and a cable plug head, wherein one end of the circuit breaker 22 is connected to the lightning conductor 26 via, for example, the connection bushing 25. By arranging the wiring sleeve and the cable plug head for the circuit breaker, the switch car of the mobile substation can be connected with a power grid more flexibly in different modes. Those skilled in the art will appreciate that the connection sleeve and the cable plug may be selected in existing products according to specific design parameters, such as the selection of a high voltage cable plug. The circuit breaker and the arrester may also be part of a high voltage switchgear (not shown), such as a GIS, i.e. a gas insulated metal enclosed switchgear, and thus be included in the high voltage switchgear. The high-voltage combined electrical apparatus is located on the semitrailer to make the switch car obtain more compact structure. Besides the breaker and the lightning arrester, the high-voltage combined electrical apparatus can also comprise devices such as a disconnecting switch, an earthing switch, a current transformer, a voltage transformer and the like, and can be provided with online detection equipment so as to reduce the time of field experiments.
