Abstract
The invention relates to an intelligent low-voltage capacitor and belongs to the electronic technical field. The intelligent low-voltage capacitor is a technical product which is organically integrated with a composite switch, a capacitor and the like. The intelligent low-voltage capacitor is characterized in that a large-sized structure mode of a traditional reactive power compensation device can be completely changed; perfect combination of measurement and control technologies and the composite switch can be realized; voltage superposition does not exist at two ends of the switch when voltage zero-crossing switching in is performed; the switching switch is controlled to be switched off in current zero crossing, so that arcing can be avoided; and therefore, the service life of the capacitor can be prolonged, and a service life withstanding millions of times of switching can be ensured. Compared with existing similar intelligent low-voltage capacitors, the intelligent low-voltage capacitor has the advantages of high reliability, low failure rate, low power consumption, long service life and the like, and can better satisfy requirements of dynamic reactive power compensation of a low-voltage power supply system.
Description
Technical field
The present invention relates to a kind of capacitor, relate in particular to a kind of intelligentized secondary capacitor, belong to electronic technology field.
Background technology
Enterprise customer wants removable parts capacitor every year, and the capacitor tripe problem that rises is never effectively solved.On the outdoor bar of electric power system, reactive power compensation case just has partly and goes wrong through the high temperature in a summer.Large because shove, fuse is easily breakdown, and part switchgear plant uses miniature circuit breaker instead.Although facilitated, had hidden danger: the connecting-disconnecting function of miniature circuit breaker only has 4000A～6000A, if there is phase fault; connection will be glued in contact, can not disconnect control loop, loses protective effect; serious time, can cause overstep tripping, expand fault face.
Summary of the invention

Further, the intelligentized secondary capacitor of above-mentioned one, it is characterized in that: described intelligent low-pressure capacitor can use by many cordwood system types, when many uses, automatically produce main frame, all the other are slave, form reactive automatic control system, indivedual fault slaves exit automatically, do not affect other machines work; Hostdown exits automatically, produces new main frame, forms new work system, intelligent strong.
Further, the intelligentized secondary capacitor of above-mentioned one, is characterized in that: described intelligent low-pressure capacitor display screen shows product operating mode and electric wiring situation, and human-computer dialogue is succinctly directly perceived.
Embodiment
A kind of intelligentized secondary capacitor, is a kind of combination switch, capacitor etc. organically to be carried out to integrated technical products, belongs to electronic technology field.Be characterized in: thoroughly changed the bulky tactic pattern of traditional reactive power compensator, realize the perfect combination of observation and control technology and combination switch, switch is in the time that voltage zero-cross drops into, there is not voltage superposition phenomenon in two ends, control fling-cut switch and in the time of current over-zero, disconnect the arcing situation that do not occur, thereby extend the useful life of capacitor and the switching life-span of 1,000,000 times of switch.
This capacitor is wanted wiring check before using first, in the situation that having controller, after wiring finishes, must check wiring, ensures without reversal connection or misconnection phenomenon, and on controller, three-phase current is sampled, and wiring is errorless and pressure-wire wiring is errorless; After finishing without wiring in controller situation, must check wiring, three-phase power line is in the right direction, without reversal connection or misconnection phenomenon, with universal instrument check three-phase power line each mutually between and whether short circuit between mutually each and shell, be allocated to " automatically " by dialling key on panel.
When many products use, each the distribution voltage that product is shown, electric current, power factor, the parameters such as reactive power should be basic identical, debug capacitor parameters as wanted, first the key of dialling on capacitor panel is pushed to " automatically " shelves, then the long left button of pressing on panel " is determined " key, now can demonstrate " UH ", as other interfaces of need, press scroll down on right button " execution " key, find the interface that needs editor, press again left button and " determine " that key enters editing interface, then switch focus by right button Update Table and with left button, finally the long left button of press " is determined " key save data and is completed setting and gets back to initial interface.
The key of dialling on capacitor panel is allocated to " throwing by force " position, after time delay 60S, drop into the first group capacitor if mend altogether capacitor, and then time delay 30S drops into the second group capacitor, it is bright that simultaneously corresponding capacitor drops into indicator light, if point benefit capacitor drops into first group of phase electric capacity after time delay 60S, then the 2S of being separated by respectively drops into another two groups of phase capacitors, and it is entirely bright that corresponding capacitor drops into indicator light.And then will dial key and be allocated to " automatically " position, excise the first group capacitor after mending altogether capacitor time delay 40S, and then time delay 30S excises the second group capacitor; Point benefit capacitor time delay 40S excises first group of phase capacitor, and the 2S of being then separated by respectively excises another two groups of phase capacitors; In aforesaid operations, be pass the test without any faulty indication.Meanwhile measuring the each phase current of capacitor with clamp on amperemeter should approach with calculated value.After off-test, make sure to keep in mind to pull back to " automatically " position dialling key.
While having external controller, product is carried out the operational order of external controller, and operation external controller makes it send the instruction that control capacitor is thrown, cut, and product should accurately be carried out; During without external controller, product will be controlled completely automatically according to no-power vacancy, throw, cut capacitor and make idle (power factor) obtain Optimal Control, in possible situation, change the idle parameter of distribution system, product should be able to be according to the throwing of idle variation automatic control electric container, cut.
The present invention has that compensation effect is better, volume is less, it is more convenient to use more flexibly, safeguard, reliability is higher, can meet better the requirement of low-voltage power supply system reactive-load dynamic compensation.
