Abstract
The invention discloses a modular middle and low-voltage reactive power compensator. In terms of functions, the apparatus mainly comprises five function modules, i.e., a control processing module, an acquisition module, a switching module, a capacitor module and a miniaturized breaker. The apparatus provided by the invention employs an innovative structural design, the function modules are reasonably distributed, installed and fixed by use of a structural member, a designed novel modular middle and low-voltage capacitor can be prevented from such defects as unreliable installation fixation, poor electrical reliability, poor maintainability and the like of a conventional reactive power compensator, and the apparatus provided by the invention has the advantages of reasonable electrical connection, firm fixation, safe and simple maintenance and the like.
Description
Technical field
This patent relates to the reactive power compensation field of electric power system, is specifically related to a kind of modularization mesolow reactive power compensator of new structure.
Background technology
Along with the develop rapidly of modern industry, more and more higher to the requirement of the quality of power supply, the economy of operation of power networks comes into one's own day by day.In modularization Medial & Low Voltage Power Network, install appropriate reactive-load compensation capacitor additional be very important, it can compensate the reactive loss of low-voltage distributing line itself and the idle needs of part of users' power consumption equipment, make idlely to reach balance as far as possible on the spot, reduce idle flowing in electrical network, this is very favourable to reducing line loss, improving quality of voltage and improve power supply capacity.
There is device strong and weak electricity system perturbations in reactive power compensator common at present, maintainable difference and device install the defect of fixing complexity etc.Particularly control treatment module, collection and switching module adopt integrated design, on the one hand, make strong and weak electricity system confusion together.Under external electromagnetic environment complicated situation, strong power system is easy to produce interference to weak electricity system, and then affects accuracy and the stability of whole system operation; On the other hand, in actual applications, reactive power compensator is mounted in modularization mesolow comprehensive distribution cabinet, once be in running status, when control treatment module needs maintenance or upgrade software, integrated design also makes staff have to device entirety be carried out disassembling work in charged situation, so not only difficult in maintenance, and there is potential safety hazard.
Summary of the invention
The object of the invention is the defect for existing reactive power compensator, and according to practical situations, provide a kind of design science, practical, safe and reliable and install modularization mesolow reactive power compensator easily.
