Problems solved by technology

Since each of the above-mentioned types of power savers has its own characteristics and limitations, it is necessary to use only any one type of power saver to achieve the best power-saving effect and full power saving effect of the entire power system. The effect of protecting electrical equipment is impossible to achieve
At present, there is no overall technical solution for effective power-saving control of a power consumption system and protection of power consumption equipment in the power consumption system

Embodiment Construction

[0022] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] This comprehensive power saving protection control system includes five types of power savers: system power saver, filter compensation power saver, frequency conversion power saver, The characteristics of the equipment, the law of electricity consumption, and the respective functions and characteristics of the five types of power savers. The five types of power savers are installed in different positions of a power system to form a comprehensive power-saving control system. In this embodiment, a system-type power saver is connected in parallel on the circuit after the main switch of the transformer outlet, which is used to suppress the transient surge in the output circuit of the transformer, and at the same time suppress a single or several high-order harmonics and improve the power factor cosΦ ; The circuit behind the system-type power...

Abstract

The invention is concerned with the complex power saving protective control system, includes the systemic power saving device, the filtering compensation power saving device, the frequency conversion power saving device, the voltage adjusting power saving device and the electromagnetism power saving device. According to the detail circs of the electricity system, the invention allocates the five types of power saving device to different locations, that is, conducts parallel connection between the systemic power saving device and the circuit after the transformer wires the switch, and with the branches of the circuit, conducts parallel connection with the filtering compensation power saving device, and conducts series connection with the frequency conversion, the voltage adjusting and the electromagnetism power saving device separately. It achieves to save power of the whole electric system and improves to clean the electric waste like surge, harmonic, and reduce the overmuch wastage, protect the equipment, and it reduces the cost of the electric usage, improves the quality of the electricity.

Description

technical field [0001] The invention belongs to power-saving protection control equipment, in particular to a comprehensive power-saving protection control system. Background technique [0002] In every power consumption system, there are many problems of power waste and excess energy consumption, only in different degrees. Power waste mainly includes transients, surges, harmonics, etc. These power wastes will seriously reduce the power consumption efficiency of the power system and electrical equipment, and have a serious impact on electrical equipment. For example, transients will cause motor The normal operating temperature increases, and for each degree of increase, the power consumption increases by about 4%; transients will form an oxide carbon film on the contact points of the motor, and the presence of an oxide carbon film per ohm of resistance, It can reduce the efficiency of the motor by 13%. Multiple harmonics will cause abnormal heating of electrical equipment,...
