Description
Technical field
The utility model belongs to dynamo-electric manufacturing field, particularly a kind of low-voltage reactive power power static compensating device.
Background technology
Low-voltage reactive power power static compensating device is mainly by form (seeing accompanying drawing 1) with the lower part:
Switch with knifeshaped fuse 1, fuse protection device 2, restriction inrush phenomenon switching contactor 3, hot relay protector 4, Shunt Capacitor Unit 5, intelligent reactive power compensating controller 6, detachable copper bar 7.
Wherein Shunt Capacitor Unit 5 is important part; It mainly acts on is the intelligent reactive power compensating controller according to for what of the lagging reactive power of electrical network load consumption; With 10～120 seconds adjustable time intervals, the input of ordering about, control Shunt Capacitor Unit automatically with cut out, make the reactive power consumption of electrical network remain at minimum state; Thereby improve power factor and grid voltage quality, reduce the reactive loss of electric line load and transformer.Because shunt capacitor operation under full and down always, as the voltage that is in operation, electric current and temperature surpassed the limit of stipulating, will shorten its useful life.The temperature rise of shunt capacitor itself, the temperature rise of bus and electric elements junction, and the temperature rise of interior insulated conductor of device and electric elements are with the useful life that directly influences Shunt Capacitor Unit.
The utility model content
The technical problem that the utility model will solve provides a kind ofly mainly to be considered from the temperature aspect, can be to the accurate static compensating device of control in addition of the temperature in the static compensating device.
A kind of low-voltage reactive power power static compensating device mainly comprises: switch with knifeshaped fuse, fuse protection device, restriction inrush phenomenon switching contactor, hot relay protector, Shunt Capacitor Unit, intelligent reactive power compensating controller, detachable copper bar, exhaust ventilation heat sink.
The exhaust ventilation heat sink is made up of exhaust ventilation fan, humiture automatic controller, resistance heating plate.
The utility model is simple, and good reliability, accuracy height are easy for installation, economical and practical.The electric property of low-voltage reactive power power static compensating device is stable behind employing the utility model, better heat-radiation effect, and inactive power compensation obviously improves.
Description of drawings
Fig. 1 is the structural representation of traditional static compensating device;
Fig. 2 is the structural representation of the utility model static compensating device;
Embodiment
As shown in Figure 1; If in switch cubicle, there are not any cooling treatment measures; Lean on the air flow of small space in the device and the airing hole on the cabinet shrouding to lower the temperature naturally fully, under long-time energising ruuning situation, each electric elements itself and lead and electric elements junction can produce certain temperature rise in the cabinet; These temperature rises influence each other to assemble and cause the interior ambient temperature of cabinet constantly to raise, and can't be reduced at short notice in the regulation safety value scope usually.Another kind of situation is that the power failure of device long period need not; Perhaps when ground temperature is low excessively, during the excessive generation condensation of humidity phenomenon; To cause the particularly insulation property destruction of electronic integrated circuit central layer of the interior electric elements of cabinet like this, form partial short-circuit, burn element in the cabinet.Aeration-cooling processing mode in the past, the one, the time is slow; The 2nd, cooling-down effect is not obvious, does not more have the heating and dehumidification function.Though shunt capacitor does not have problem in short-term, long-play still will shorten its useful life, when serious even burn shunt capacitor, therefore has potential safety hazard all the time.
The utility model low-voltage reactive power power static compensating device is mainly by form (seeing accompanying drawing 2) with the lower part:
Switch with knifeshaped fuse 1, fuse protection device 2, restriction inrush phenomenon switching contactor 3, hot relay protector 4, Shunt Capacitor Unit 5, intelligent reactive power compensating controller 6, detachable copper bar 7, exhaust ventilation heat sink.The exhaust ventilation heat sink is made up of exhaust ventilation fan 8, humiture automatic controller 9, resistance heating plate 10.
The technical conceive of the utility model is: like Fig. 2, according to the cross-ventilation characteristics, install an exhaust ventilation fan 8 additional at bottom of cabinet bulk; A matching used humiture automatic controller 9 is installed again; It can be according to the in-cabinet temperature rising situation of change of (comprise and work as ground temperature); Set a temperature limit; In case temperature rise reaches this limit value in the cabinet, humiture automatic controller 9 starts exhaust ventilation fan 8 at once and carries out cold and hot air exchange, reaches rapid cooling purpose.Humiture automatic controller 9 can also be according to the situation of (comprising the local environment atmospheric humidity) of air humidity in the cabinet; Set an air humidity limit value, in case the interior air humidity of cabinet reaches or near this limit value, humiture automatic controller 9 is starting resistance heating plates 10 at once; Produce wet air in the heat energy heating cabinet rapidly; Make air humidity decline in the cabinet, and remain on normal level, realize accurately control.So just can let the long-time safe operation of shunt capacitor, thereby realize the purpose of reactive power static compensation.
The utility model technology is simple, easy-to-connect, accurate, the good cooling effect of control, and cost is lower.The utility model is verified through experimental prototype, and is obtained good result.
