Abstract
The utility model relates to a socket device of a reactive power compensation capacitor, which comprises a three-phase socket (1) and a three-phase plug (2), and is characterized in that the reactive power compensation capacitor (3) is parallelly connected between the live wire and the neutral line of the three-phase socket (1); and the socket device of the reactive power compensation capacitor also comprises an outer shell (6) which contains the three-phase socket (1) and is used for protecting the use. The utility model has the beneficial effects that the socket of the reactive power compensation capacitor can supply corresponding reactive power to connected electric loads, such as motors, electric tools, household electric appliances and other sensitive loads, so that the reactive power which is supplied to the sensitive loads by a power supply of a power grid and is transmitted by a line is reduced; and because the flow of the reactive power in the power grid is reduced, the electricity loss of the line and a transformer due to the transmission of the reactive power can be reduced, and a power-saving effect is significant.
Description
Technical field
The utility model relates to a kind of socket device, relates in particular to a kind of reactive-load compensation capacitor socket device.
Background technology
Electric load in the electrical network such as motor, electric tool, household electrical appliance etc., major part belongs to inductive load, and in running, needing provides corresponding reactive power to these equipment.In electrical network, install after the reactive-load compensation equipment such as shunt capacitor; The reactive power that can provide inductive load to consume; Reduced the reactive power that electric network source provides, carried by circuit to inductive load; Owing to reduced reactive power flowing in electrical network, therefore can reduce the electric energy loss of circuit and transformer because of carrying reactive power to cause, reach power savings.Can also adjust the three-phase imbalance electric current through appropriate reactive-load compensation method.Capacitor in cross-over connection between phase and phase can be in alternate transfer active current.Therefore; System for three-phase current unbalance; As long as rightly each between phase and phase and each mutually and insert the capacitor of different capabilities between the zero line, not only can the power factor of each phase all be compensated to 1, and can make the active current of each phase reach poised state.
And inductive load is carried out reactive power compensation on the spot, be the most perfect compensation way: capacitor is directly parallelly connected with inductive load, drops into simultaneously or stops using; Can make and idlely not flow backwards; Guarantee that the user power factor is in hysteretic state all the time, both helped the user, also help electrical network.Help reducing inductive load motor starting electric current, reduce the spark of contactor, improve the reliability of control apparatus work, prolong the useful life of motor and control appliance.
But reactive power compensation on the spot is used also not extensive at present; Though air conditioner, washing machine, electric fan, most of energy-saving electric refrigerator, part motor etc. self have been with the operation capacitor; Realized reactive power compensation on the spot; But most of inductive load in use also is in uncompensated state, is unfavorable for energy-conservation.
The utility model content
The purpose of the utility model is the deficiency to prior art, is necessary to provide a kind of reactive-load compensation capacitor socket device, have economize on electricity obvious, easy to use, be easy to carry, inexpensive characteristics.
The utility model solves the existing uncompensated technical scheme of inductive load: a kind of reactive-load compensation capacitor socket device; It comprises three-phase socket (1) and 3-phase plug (2); Wherein, A parallelly connected reactive-load compensation capacitor (3) between the live wire of said three-phase socket (1) and zero line, said reactive-load compensation capacitor socket device also comprise the shell (6) that is used to protect said three-phase socket (1) in said three-phase socket (1) is housed in.
As the further improvement of such scheme, said reactive-load compensation capacitor socket device also comprises the live wire that is connected on said three-phase socket (1) and the electric current fuse (4) between the said reactive-load compensation capacitor (3).
As the further improvement of such scheme, said reactive-load compensation capacitor socket device also comprises the discharge resistance (5) that is connected in parallel on the said reactive-load compensation capacitor (3)
Said reactive-load compensation capacitor socket device inserts three-phase socket with this inductive load, inserts electrical network by 3-phase plug again, and is parallel with reactive-load compensation capacitor between the live wire of three-phase socket and zero line, to realize reactive power compensation on the spot, reaches the purpose of saving electric energy.

Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As depicted in figs. 1 and 2; The utility model comprises the three-phase socket 1 that inserts inductive load, inserts power supply 3-phase plug 2, parallelly connected reactive-load compensation capacitor 3 between live wire L and zero line N; Series current fuse 4 between live wire and the capacitor 3, discharge resistance 5 is connected in parallel on the capacitor 3.Whole socket is by shell 6 protections.
Please combine Fig. 3, reactive-load compensation capacitor C is parallel to inductive load, plays the effect of local compensation, reaches energy-conservation effect.Electric current fuse F is series on the live wire L of circuit, if the situation of overcurrent meeting open circuit guarantees safety.Discharge resistance R can be rapidly to capacitor C discharge, prevent that inductive load from receiving impact, increase the fail safe of whole device.
It is a kind of reactive-load compensation capacitor socket that the foregoing description only is used for further specifying the utility model; But the utility model is not limited to embodiment; Every technical spirit according to the utility model all falls in the protection range of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
