Storage and transportation equipment for outdoor type removable impulse voltage generator

Abstract

The invention relates to storage and transportation equipment for an outdoor type removable impulse voltage generator, comprising two containers for holding the impulse voltage generator, wherein the container bearing the horizontal impulse voltage generator body is provided with an epoxy bucket which is sleeved outside an assembled matrix of the impulse voltage generator body and is fixed on a base of the impulse voltage generator body, sliding guides with grooves and an axis of rotation fixed on the lower bottom edge of the base of the horizontal impulse voltage generator body; the two endsof the axis of rotation are provided with rollers arranged in the grooves of the sliding guides; and the other container is provided with a fixing device of equalizing rings of the impulse voltage generator body, a fixing device of a weakly damped capacitive voltage divider of the impulse voltage generator and a clamping device of a direct-current charger of the impulse voltage generator. The equipment can be used for transporting the assembled impulse voltage generator body and is simple in structure, convenient to use, beneficial to guaranteeing the performance of the impulse voltage generator to be transported and low in transportation cost.

Description

technical field [0001] The invention relates to storage and transportation equipment of an outdoor movable impulse voltage generator. Background technique [0002] With the modernization of the national economy and the continuous improvement of people's living standards, the widespread application of electrical equipment and the increasing development of the aerospace industry, the gap in energy and power is getting bigger and bigger. In order to meet the demand, the single-unit capacity of the grid has grown from about 100MW to 200-300MW , ultra-high-voltage long-distance power transmission increases, and an accident occurs in a unit, which has huge impact and loss. Therefore, it is required that the power supply is highly safe and reliable, and the voltage frequency is qualified. In order to meet this demand, the transmission voltage level of power grid power is gradually increased. With the development from high voltage to ultra-high voltage and then to ultra-high voltage...

Problems solved by technology

[0003] At present, the million-volt (1000kV voltage level) line that our country is doing its best to build is the most cutting-edge and comprehensive power construction project in the world. A number of UHV bases are specialized in the basic technology research of UHV power grids, and these research bases are inseparable from basic test equipment such as impulse voltage generators. Since impulse voltage generators are large-scale equipment, the transportation and assembly projects are relatively large. The requirements for manpower and material resources are relatively high. According to the traditional method, the impact test of power equipment requires a large number of supporting power equipment (such as power transformers, high-voltage switches, high-voltage transformers, power cables, insulators, lightning arresters, bushings and high-voltage complete sets of equipment, etc.) after assembly, the lightning impact test, operation impact test and special impact test, etc., are qualified to leave the factory. All electrical equipment is assembled after long-distance transportation to the site. The assembly time often takes more than ten days, and after long-distance transportation , the state of the equipment has changed before it is put into operation or power-off maintenance, and local defects cannot be detected through traditional steady-state tests. These defects will not be reflected when the equipment is in normal use. When it is in an abnormal state, such as Local defects will be revealed only when the switch is switched on and off, transient overvoltage in the system, etc., causing accidents. It can be seen that the current transportation method of parts in bulk and the traditional detection method are no longer suitable for today's high requirements.
