The emergency power car is an indispensable special vehicle for the operations of China's power, telecommunications, mobile, and China Unicom. In recent years, social needs have become increasingly diversified. Bypass vehicles and vehicles in disguise have emerged. These three types of emergency rescue vehicles can cope with unexpected power supply accidents and power supply requirements during natural disasters. Since the functions of the three emergency vehicles are different, these vehicles are selectively used according to the specific conditions.
Three kinds of special vehicles needed by power companies: First, emergency power car
Emergency power car
The emergency power car is a special vehicle with a power supply device, which is mainly composed of an automobile chassis, a diesel generator set, transmission and distribution and operating systems, an efficient sound-absorbing and noise-reducing noise-reducing cabinet, an intake and exhaust air noise reduction system, and an exhaust noise elimination system. , lighting systems, hydraulic support systems, cable winches and tools and equipment cabins and other components.
The emergency power supply vehicle will repair and pre-test the original high-voltage power distribution lines and equipment without power failure. For the urban distribution overhead lines and equipment, together with the high-voltage bypass cable car, a temporary bypass is built to complete the high-voltage power distribution. Uninterrupted overhaul or pretest of lines and equipment.
The power car adopts an exempted excitation generator. This generator can maintain a stable voltage, easy maintenance, once it is soaked, it can be reused within 6 hours. Due to excellent electromagnetic compatibility, the power car can operate in thunderstorms. In addition, the power generation efficiency can also be increased by 10-15%.
At present, there are many companies in China that have done a good job in emergency power supply vehicles. Haidexin in Longyan County is a typical one. The manufacturer's emergency power car mainly uses a 4*2 or 6*4 chassis, which is small in size and can be operated flexibly. At the same time, the power car produces less than 85 decibels during operation.
In addition to cable winches, power cables, hydraulic legs, lightning arresters and other standard, Haidexin's power car also provides ISS intelligent service system, lighting lift lights, engineering warning lights, quick plugs, fire suppression king, fuel water jacket heaters, Optional equipment such as fuel pump, driving recorder, and ATS dual power supply switch to meet the diverse needs of customers.
Three special vehicles required by power companies: Second, bypass vehicles
Bypass operation vehicle
Like the emergency power car, the bypass work vehicle is also a kind of emergency rescue vehicle for power supply. The car body is painted with engineering yellow. It is generally composed of a truck chassis, a carriage assembly, a fully automatic cable winding unit, a dedicated accessory storage shelf, and a cable control system. Depending on the length of different bypass operations, a bypass operation cable car of different number of meters may be selected.
The interior of the bypass car adopts a partition design, which can store bypass cables and accessories at the same time. The side protection device can replace the side protection when the skirt structure is used. The rolling shutter doors and flip-up pedals on both sides of the vehicle are convenient for storing tools; the chassis has hydraulic support. Legs, the vehicle can play a supporting role when lifted.

This type of vehicle is mainly used for power line repair and transformation, the need for power outage processing, at this time the use of bypass diversion line, bypass flexible cable, bypass intermediate connector, bypass mobile box change repair car and other equipment The combination of building blocks forms a bypass channel, and then the switches, switch gates, or lockers that need to be repaired are isolated from the power grid, so as to ensure that the power supply line will not affect the continuous power supply to the user during the power outage repair process. It is an important means to reduce the power outage time.
Three kinds of special vehicles required by power companies: Third, vehicles in disguise
Phased vehicles appear to be relatively late with respect to mobile power vehicles and bypass vehicles. This kind of truck is mainly aimed at the replacement of transformers. When one of the transformers fails and requires power failure for maintenance, the phase-changed vehicle can maintain the normal power supply in the fault area by moving the transformer.
As it is a new product, there are fewer manufacturers currently producing variant vehicles. In the Suizhou area, only Olong family is manufacturing.
At present, three kinds of live working vehicles, such as emergency power supply vehicles, bypass vehicles, and phase-change vehicles, have gradually become “killers†for reducing power outage time in various regions. With the development of urban construction, the demand for three kinds of vehicles will increase in each region in the future. If a car company wants to quickly open this market, it needs to provide the vehicle's storage time, stability and reliability.
Haixing brush machines have been well accepted by the markets because of the stable and reliable features. Haixing has been in the brush making industry for more than twenty years, and on the basis of international advanced brush making technology and our own patented inventions, Haxing has become a famous brand in Chinese brush making field.
