The special electric power vehicle is used as a special vehicle for emergency repair engineering, and is mainly used for enabling an electric power company to respond in time and quickly repair electric power equipment when an electric power failure occurs or the electric power equipment is replaced routinely so as to ensure that power failure is reduced or not stopped, and therefore electric power personnel and the electric power equipment can be quickly transported to an operation site and put into operation. However, the existing electric power special vehicle needs to carry a large amount of electric power operation special equipment, some of which are large-scale electric power equipment, such as a ring main unit, a transformer, a generator set and the like, and thus the chassis needs to have larger space and carrying capacity, so that the existing electric power special vehicle is mostly refitted into the special electric power vehicle through a second type of chassis.

The height of the upper plane of a girder of the light chassis of the special electric power vehicle from the ground is 700mm, the height of an auxiliary frame is 180mm, the height of large-scale electric power equipment special for electric power is about 1400mm generally, and the wall thickness of the top of a carriage is 60mm, so that the height of the whole vehicle reaches about 2340 mm. And according to the 'garage building design Specification' JGJ100-98, the minimum clear height mini-car and small-car in the garage are regulated to be 2.2 meters. Therefore, the underground parking garages in the residential areas are mostly constructed by adopting the height limit of 2.2 meters, so that the special electric power vehicle carrying large-scale electric power equipment cannot enter the garage for electric power overhaul or rush repair due to the limitation of the height of the garage.

The main solution at present is to stop the special electric power vehicle on a district road and access the basement power distribution room of the district through a cable. The disadvantages of this method are: 1. the method occupies the community road and influences the passing of pedestrians and vehicles; 2. because a part of cables are connected with a 10kV high-voltage line, potential safety hazards exist, a large number of safety protection measures and special persons need to be arranged on an operation site to take care of preventing pedestrians from approaching the operation site to cause danger; 3. the cable needs to be dragged into a basement power distribution room in a long distance, so that time and labor are wasted, and the efficiency is low; 4. part of electric power operation is noisy, and the noise disturbs residents because vehicles are parked close to residential buildings.
