Three-phase voltage stabilizer for long-distance temporary power supply of single-phase generator

Abstract

The invention provides a three-phase voltage stabilizer for the long-distance temporary power supply of a single-phase generator. In the invention, only a main circuit and a control circuit, before a voltage stabilization part, of the three-phase voltage stabilizer are changed independently of the voltage stabilization form of the voltage stabilizer. Therefore, the invention is applied to the voltage stabilizers of various voltage stabilization forms, such as parameter voltage stabilizers, mechanical voltage regulation and compensation type voltage stabilizers, inductive voltage regulation type voltage stabilizers and novel silicon controlled contact-free stabilizers. In the three-phase voltage stabilizer, three switch components are arranged at the rear end of a power input switch QF; and when temporarily supplying power to a base station in the power failure of a power grid, the heavy single-phase fuel generator does not need transporting to the communication base station on a mountaintop and can temporarily supply the power to a rectifier cubicle of the base station at a long distance by utilizing a low-voltage distribution line so as to reduce workload, save time, save labor and greatly improve the working efficiency. The three-phase voltage stabilizer has good social benefits.

Description

technical field [0001] The invention relates to a three-phase voltage stabilizer used for long-distance temporary power supply of a single-phase generator. Background technique [0002] With the popularization of mobile phones and the promotion of 3G communication services in my country, the construction of communication base stations is also in full swing. Communication base stations are all chosen to be built next to traffic arteries or in densely populated areas. In order to increase the coverage radius, communication base stations in mountainous areas are chosen to be built at altitudes. on a relatively high hilltop. The alpine base station is an unattended base station. The road up the mountain is a winding and rugged path or basically no road. The building materials and equipment of the base station are carried to the top of the mountain by horses. It takes half an hour or even more than an hour to climb the base station with bare hands. . In order to reduce the const...

AI Technical Summary

Problems solved by technology

However, it is extremely difficult to transport the heavy generator to the communication base station on the top of the mountain, which is time-consuming and labor-intensive, which greatly reduces the work efficiency

Is it possible not to move the generator to the base station in the high mountain, connect the generator at the beginning of the transmission line down the mountain, and use the long-distance transmission line to temporarily supply power to the base station temporarily, which requires the voltage stabilizer to withdraw from the voltage regulation and only send a single signal to the rectifier panel Phase alternating current, this is a technical problem that the existing three-phase power regulator technology has not been able to realize
