Embodiment 1

[0029] like figure 1 The section diagram of the main equipment interval of the GIS substation shown in the present embodiment is a new type of vehicle-mounted GIS substation, including the car body 1, the chassis 2 and the main equipment of the GIS substation, and the main equipment of the GIS substation is installed on the car body 1 through the chassis 2. The main equipment of the GIS substation is horizontally arranged on the car body 1 at multiple intervals. The main equipment of the GIS substation includes a busbar three-position switch 3, a circuit breaker 4, a current transformer 5, a three-position switch 6, a quick grounding switch 7, Arrester 12.

[0030] The three-station switch 3 of the busbar adopts the structure of the lower structure and is connected to the circuit breaker 4; the three-station switch 6 is connected to the circuit breaker 4 through the current transformer 5; the quick grounding switch 7 is installed on the three-station switch 6, and the lightnin...

Embodiment 2

[0036]Based on the aforementioned vehicle-mounted GIS substation, this embodiment provides a method for installing the aforementioned new vehicle-mounted GIS substation, including the following steps:

[0037] (1) Factory prefabrication: The overall prefabrication of the main equipment of the GIS substation is realized in the factory, and the modular division is carried out according to the requirements. Multiple equipment intervals are arranged horizontally on the chassis on the vehicle body, and the overall connection and integrated chassis are adopted; The expansion joints are used to connect the modules; and the wiring and debugging of the overall equipment are completed in the factory;

[0038] (2) Equipment dismantling: Disassemble the cable tank outlet and cable tank support according to the position of the equipment dismantling surface, so as to meet the 3-meter width limit standard for road transportation;

[0039] (3) Transportation: The main equipment is transported...

Abstract

The invention discloses a novel vehicle-mounted GIS substation and an installation method thereof, The vehicle-mounted GIS substation comprises a vehicle body, a chassis and a GIS substation main bodyequipment, wherein the GIS substation main body equipment is arranged on the vehicle body at a plurality of spacing laterally, and comprises a bus bar three-station switch, a circuit breaker, a current transformer, a three-station switch, a fast grounding switch and a lightning arrester. The busbar three-station switch adopts a mechanism lower structure and is connected with a circuit breaker. The three-station switch is connected with the circuit breaker through the current transformer. A quick ground switch is mounted on the three-station switch, A lightning arrestor is connected with a three-station switch through a connecting bus, and the lightning arrester is directly installed on the chassis through bolt pillars, and is connected with the chassis together with the circuit breaker, the structure is compact and reasonable, the modular assembly and transportation can meet the requirements of the basic highway transportation, can be adjusted according to the actual situation of thepower station, the construction cost of the station is low, the efficiency is high, and the requirement of the vehicle-mounted substation for the power network construction is met.

Description

technical field [0001] The invention belongs to the technical field of mobile substations, in particular to a novel vehicle-mounted GIS substation and an installation method thereof, which are applied to a GIS vehicle-mounted substation with a rated voltage level of 145kV. Background technique [0002] With the acceleration of urban construction, the increase of grid load, and with the development of power transformation and distribution technology, vehicle-mounted substations are developing rapidly. Especially in projects such as reconstruction and expansion of old stations, emergency power supply of power grids, etc., vehicle-mounted substations are more and more favored by users because of their strong flexibility and mobility. However, the GIS vehicle-mounted substations currently on the market are mainly vehicle-mounted substations with a single-interval line substation structure, which has a single function. When a multi-interval GIS substation is required, multiple ve...
