Through the support that is used for installing electrical components in the internal setting of cabinet for electrical components's installation is orderly, the internal space of rational utilization cabinet, and conveniently look for and the handling failure.
Description
Technical field
The utility model belongs to field of electrical control, particularly relates to a kind of support installed for power back-off cabinet electronic component.
Background technology
Alternating-current is in by pure resistance, and electric energy has all changed into heat energy, and in by pure capacitive or the load of pure perception, does not do work. That is do not consume electric energy, it is wattless power. Certainly actual load, can not be pure capacitive load or the load of pure perception, general is all Combination load, such electric current is by them, just having part electric energy not do work, be exactly wattless power, power factor now is less than 1, in order to improve the utilization ratio of electric energy, reactive-load compensation will be carried out.
This kind of power can cause voltage-drop (during inductive reactance) or voltage to raise (during capacitive reactance) and joule (resistance heating) loss in electrical network, but can not make effective merit. Thus need wattless power to be compensated. Reasonable disposition reactive-load compensation (where comprise, with much capacity and adopt which kind of pattern) is an important content in Power System Planning and design effort. In operation, reasonable employment reactive compensation capacity, the flowing of control wattless power is one of groundwork of power system scheduling.
The effect of reactive power compensation cabinet is the electric substation in power system or directly at electric energy user electric substation installing wattless power power supply, to change the flowing of wattless power in power system, thus improve the voltage level of power system, reducing via net loss and improve the dynamic property of power system, this kind of technical measures are called that wattless power compensates.
Reactive power compensation cabinet in existing market, when installing electronic component in cabinet, owing to not setting the support of installation, thus in installation process, the arrangement of electron device and circuit is often very in disorder, is unfavorable for making full use of space in cabinet on the one hand; On the other hand, when a failure occurs it, can not Timeliness coverage trouble spot and fix a breakdown in time.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of support installed for power back-off cabinet electronic component, by pre-setting mounting bracket in cabinet, make the installation spacial ordering at electronic component, make full use of space in cabinet, conveniently find out trouble spot and get rid of.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of support installed for power back-off cabinet electronic component, the two pieces of mounting plates comprise the fixed strip being horizontally set in cabinet wall upper, middle and lower, left and right sides end, being vertically arranged in cabinet wall middle, the left and right sides and the some crossbeams being horizontally set between mounting plate, be fixed with shelf in the bottom of support.
As preferably, described mounting plate is U-shaped, multiple open holes has evenly been offered on the bottom of mounting plate and two sides.
As preferably, described crossbeam evenly being offered the long hole of multiple arranged transversely.
Compared with prior art, the invention has the beneficial effects as follows: the support for installing electric elements is set in cabinet so that the installation of electric elements is orderly, the space in Appropriate application cabinet, and easy-to-look-up and process fault.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
One as shown in Fig. 1��Fig. 5 is used for power back-off cabinet electricity, comprise cabinet 1, and Intelligent reactive power compensation device 2, knife switch 3, mutual inductor 4, fusible cut-out 5, contactor 6, thermo-relay 7 and some the compensating condensers 8 being arranged in cabinet 1 of arranging successively from top to bottom; Electrical network power supply is connected in series knife switch 3, mutual inductor 4, fusible cut-out 5, contactor 6, thermo-relay 7 and compensating condenser 8 successively by wire 20; Described mutual inductor 4 and Intelligent reactive power compensation device 2 feedback link; The throwing of Intelligent reactive power compensation device 2 control and compensation electrical condenser 8 is cut; Hot condenser is electrically connected with Intelligent reactive power compensation device 2; Fusible cut-out 5 is also electrically connected with thunder arrester 9. Electrical network power supply is connected from the circuit accessed between mutual inductor 4 by vertical bus 10.
In the circuit of this reactive power compensation cabinet, by mutual inductor 4, power factor being fed back to Intelligent reactive power compensation device 2, the throwing being carried out control and compensation electrical condenser 8 by Intelligent reactive power compensation device 2 is cut; When power factor is very high; the disconnection on Intelligent reactive power compensation device 2 control and compensation electric capacity road, when power factor is not high, the operation of Intelligent reactive power compensation device 2 control and compensation circuit; thus protect compensating condenser 8, extend the life-span of compensating condenser 8.
Fig. 3��Fig. 5 gives the structure of mounting bracket in cabinet, this support comprises the fixed strip 11 being horizontally set in cabinet 1 left and right sides wall upper, middle and lower end, be vertically arranged in cabinet 1 left and right sides wall middle two pieces of mounting plates 12 and the some crossbeams 13 being horizontally set between mounting plate 12, Intelligent reactive power compensation device 2, knife switch 3, mutual inductor 4, fusible cut-out 5, contactor 6, thermo-relay 7 are from top to bottom fixed on the crossbeam 13 of different heights successively. The shelf 14 for shelving compensating condenser 8 it is fixed with in the bottom of support. Mounting plate 12 is U-shaped, and multiple open holes 15 has evenly been offered on the bottom of mounting plate 12 and two sides. Crossbeam 13 is evenly offered the long hole 16 of multiple arranged transversely. Support for installing electric elements is set in cabinet 1 so that the installation of electric elements is orderly, the space in Appropriate application cabinet 1, and easy-to-look-up and process fault.
