Abstract
The utility model provides a self -healing low pressure power capacitor circuit that connects in parallel, capacitance compensation cabinet, circuit breaker, once insurable, switch, the parallelly connected power capacitor of self -healing low pressure establish ties, arrester one end the circuit breaker with once insurable between parallelly connected, other end ground connection, after secondary insurance, contactor, electric capacity switching controller, condenser temperature switch establish ties it is once parallelly connected between the insurable and arrester. The utility model discloses can effectively avoid the parallelly connected power capacitor self -healing of self -healing low pressure failure back, cause component insulation level to reduce or the short circuit, produce the drum tripe, burst, cause the peril condition such as electricity distribution room fire even, very big improvement the factor of safety of electricity distribution room, can also avoid because of a certain the component in condenser inside because the self -healing failure leads to insulating decline, in addition the short circuit, facilitate the insurable action of temperature electric current, lead to the capacitance constantly to descend, the finally emergence of the condenser afunction condition.
Description
Technical field
The utility model relates to a kind of self-healing low-voltage the parallel power condenser, particularly a kind of self-healing low-voltage the parallel power condenser with temperature protection.
Background technology
Current, for reducing the loss in electric power conveying, improve capacity and the quality of electric power conveying, must carry out reactive power compensation, self-healing low-voltage the parallel power condenser widely uses as the reactive power compensation gesture of electric power system.In actual motion, although self-healing low-voltage the parallel power condenser has self-healing function, more safe and reliable, but still there is the situation of self-healing failure, cause element insulating level to reduce, even short circuit, produce bulge, explosion, even cause switchgear house fire.Some capacitor internal set temperature current insurance device, when some elements because insulation during self-healing failure declines, even during short circuit, thermocurrent can be produced, facilitate temperature current safe action, this element is at once out of service, and whole capacitor still can continue normal operation, but capacitance capacity can constantly decline, final loss of function.
Summary of the invention
For solving the problem, the utility model provides a kind of self-healing low-voltage the parallel power condenser circuit.
The technical solution adopted in the utility model is: a kind of self-healing low-voltage the parallel power condenser circuit, capacitor compensation cabinet, circuit breaker, once insurance, switch, the series connection of self-healing low-voltage the parallel power condenser, lightning arrester one end circuit breaker with once insure between in parallel, other end ground connection, after the series connection of secondary fuse, contactor, capacitor switching controller, capacitor temperature switch, in parallel with between lightning arrester in described once insurance.
Especially, described capacitor switching controller controls described contactor action.
Especially, the disconnection, closed of described contactor control switch.
Preferably, described capacitor temperature switch-linear hybrid is in the case surface of self-healing low-voltage the parallel power condenser.
Preferably, between switch and self-healing low-voltage the parallel power condenser, be also arranged in parallel a capacitor and drop into signal lamp.
When capacitor case temperature switch reaches predetermined temperature, capacitor temperature switch motion, capacitor temperature make and break contact disconnects, capacitor switching controller control contactor switching, contactor switching control switch disconnects, then self-healing low-voltage the parallel power condenser main line open circuit, self-healing low-voltage the parallel power condenser is excised.Capacitor drops into signal lamp and is connected on contactor lower end, and now capacitor drops into signal lamp and do not work because of dead electricity.
When capacitor temperature switch temperature drops to certain value, self-healing low-voltage the parallel power condenser drops into again.
If self-healing low-voltage the parallel power condenser drops into repeatedly, capacitor drops into signal lamp and switchgear house operator on duty can be reminded to change this self-healing low-voltage the parallel power condenser.
After the utility model effectively can avoid self-healing low-voltage the parallel power condenser self-healing failure, cause element insulating level to reduce or short circuit, produce bulge, explosion, even cause the dangerous situations such as switchgear house fire, greatly improve the coefficient of safety of switchgear house; Can also avoid because of the some elements of capacitor internal because self-healing unsuccessfully causes insulation to decline, even short circuit, facilitates temperature current safe action, and cause capacitance capacity constantly to decline, final capacitor function loses the generation of situation.

Embodiment
As shown in Figure 1, a kind of self-healing low-voltage the parallel power condenser circuit, capacitor compensation cabinet 1, circuit breaker 2, once insure 5, switch 11, self-healing low-voltage the parallel power condenser 9 connect, lightning arrester 3 one end circuit breaker 2 with once insure 5 between in parallel, other end ground connection; After the series connection of secondary fuse 4, contactor 7, capacitor switching controller 6, capacitor temperature switch 10, in parallel with between lightning arrester 3 in described once insurance 5.Described capacitor switching controller 6 controls described contactor 7 switching, the disconnection of described contactor 7 switching control switch 11, closed.Described capacitor temperature switch 10 is arranged on the case surface of self-healing low-voltage the parallel power condenser 9.Between switch 11 and self-healing low-voltage the parallel power condenser 9, be also arranged in parallel a capacitor and drop into signal lamp 8.
When capacitor case temperature switch 10 reaches predetermined temperature, capacitor temperature switch 10 action, capacitor temperature switch 10 contact disconnects, capacitor switching controller 6 control contactor 7 switching, contactor 7 control switch 11 disconnects, then self-healing low-voltage the parallel power condenser main line open circuit, self-healing low-voltage the parallel power condenser 9 is excised.Capacitor drops into signal lamp 8 and is connected on contactor 7 lower end, and now capacitor drops into signal lamp 8 and do not work because of dead electricity.
When capacitor temperature switch 10 temperature drops to certain value, capacitor temperature switch 10 closes, and self-healing low-voltage the parallel power condenser main line is connected, and self-healing low-voltage the parallel power condenser 9 drops into again.
If self-healing low-voltage the parallel power condenser 9 drops into repeatedly, capacitor drops into signal lamp 8 and switchgear house operator on duty can be reminded to change this self-healing low-voltage the parallel power condenser 9.
