Description of drawings
Fig. 1 is the structural representation of a kind of execution mode of the utility model.
Fig. 2 is the structural representation of the another kind of execution mode of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation..
Embodiment 1
As shown in Figure 1, described in the utility model have an electricity saving function electrical power distribution switches cabinet, on electrical power distribution switches cabinet bus, be in series with the first switch XKW1, power-saving module and the 3rd switch XKW3 successively, electric current is diverted to each minute circuit through behind the power-saving module, and each switch-dividing control distribution arrives load on the circuit by dividing again.It is in parallel with the first switch XKW1, power-saving module and the 3rd switch XKW3 also to be provided with second switch XKW2 on the bus.
Described switch replaces with circuit breaker, can automatic or manual under the fault of power-saving module or non-electricity-saving state disconnects, closed to ensure that power supply state is normal.
Wherein said power-saving module comprises reactor device, three-phase voltage bascule, harmonic wave or surge absorption device and reactive power compensator.Described various piece must be installed in the art, all is ripe module, so the utility model is not analyzed with regard to concrete apparatus structure.And, in this area,, also have to comprise that the product that above each device matches is selective also relevant for power-saving module.
In specific product is used, power-saving module can be chosen as reactive power compensator, three-phase voltage bascule according to the requirement of factors such as field of employment and cost, be used for absorbing one or more combination of the reactor device of harmonic wave or surge and variable frequency control apparatus.Such as, power-saving module can singly select reactive power compensator, perhaps other three kinds of devices.Power-saving module also can be selected reactive power compensator and the combination of three-phase voltage bascule, perhaps wherein any two kinds combination.Power-saving module also can be selected the combination of reactive power compensator, three-phase voltage bascule and reactor device, perhaps wherein any three kinds combination.Power-saving module also can comprise reactive power compensator, three-phase voltage bascule simultaneously, be used to absorb the reactor device and the variable frequency control apparatus of harmonic wave or surge.
