Specific embodiment

It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.

As shown in Figure 1 to Figure 3, this low voltage switch equipment, comprising:

The framework 100 formed is built by profile, the framework 100 forms four function counters, each function by longitudinal subdivision The top of cabinet is by laterally separated formation bus-bar room 100a, and bus-bar room 100a is interior to be equipped with bus duct 500, and the back side of bus-bar room 100a is solid Equipped with ventilation front plate 810, the bottom of each function counter is by laterally separated formation draft chamber 100b, the front of draft chamber 100b and back Face is equipped with ventilation front plate 810, and ventilation fence 810 is offered on the ventilation front plate 810, is also cut with scissors in the middle part of the back side of each function counter It is connected to cabinet door 600；

Aspiration pump 700 is equipped in each draft chamber 100b, aspiration pump 700 includes two horizontally disposed air inlets 710, Two air inlets 710 are respectively facing the front of draft chamber 100b, the back side, and aspiration pump 700 includes vertically disposed gas outlet 720. That is two ventilation fences 810 at two air inlets 710 against the front draft chamber 100b, the back side extract air, and pumping efficiency is higher, whole Body better heat-radiation effect, 810 structure of ventilation fence can enter aspiration pump 700 to avoid foreign matter, and air extraction structure is relatively reliable.

In actual application, there are also the metal plates for covering 100 structure of framework other than 100 structure of framework for low voltage switch equipment Golden part is used to integrally closed low voltage switch equipment, avoids internal electrical component exposed.

For the utility model by the way that aspiration pump 700 is arranged in the bottom of function counter, two air inlets 710 of aspiration pump 700 are right Quasi- ventilation fence 810, gas outlet 720 vertically upward, so that Cryogenic air is pumped into function counter, according to the principle that hot-air rises with And the effect of air pressure, Cryogenic air are oppressed the hot-air inside function counter and are discharged along the ventilation fence 810 of top bus bar room 100a, from And the internal temperature of function counter is reduced, the airflow channel in the structure is corresponding with the motion profile of hot-air, and heat dissipation effect is more It is good.

Side, bottom surface, the top surface of each draft chamber 100b is equipped with demarcation plate 900, demarcation plate 900 and ventilation front plate 810 Demarcation plate 900 is stretched out in the gas outlet 720 of common enclosed ventilation room 100b, the aspiration pump 700 upwards.

Draft chamber 100b is closed by setting demarcation plate 900, makes draft chamber 100b that low pressure space be more readily formed, mentions The pumping efficiency of high aspiration pump 700, makes more Cryogenic air entered function cabinets, and better heat-radiation effect is upward by gas outlet 720 Demarcation plate 900 is stretched out, makes Cryogenic air that the Cryogenic air being pumped into be avoided directly to flow out from bottom, influences heat dissipation effect.

The inside of each ventilation front plate 810 is equipped with the filter screen of covering ventilation fence 810, enters pumping to avoid impurity such as dusts Air pump 700 and function counter influence the stability and safety of equipment.

Two in four function counters are outgoing line cabinet 130, and outgoing line cabinet 130 is by laterally separated several switch gear rooms of formation 131, each switch gear room 131 is equipped with the drawer unit 200 of preset height, and mutually level drawer unit 200 can be replaced mutually； Each drawer unit 200 includes drawer panel 220, and drawer panel 220 is equipped with rotary switch 221, state table 222, label frame 223 With two handles 224, rotary switch 221 controls the electrical on-off of drawer unit 200, rotation turn switch 221 to disconnection simultaneously State can extract drawer unit 200 out, and two handles 224 are symmetrical arranged the two sides with drawer panel 220.

I.e. by rotary switch 221 to drawer unit 200 realize mechanical caging, drawer unit 200 in the energized state without Method is extracted, to guarantee safety.In addition, setting label frame 223 is used to mark the serial number of drawer unit 200 in order to user Identification.Also, by being symmetrical arranged two handles 224 in the left and right sides of drawer panel 220, taking out drawer unit 200 When out can two sides simultaneously stress, avoid unilateral stress cause drawer unit 200 misplace.

Other two function counter is respectively incoming line cabinet 110, capacitor box 120, and the front upside of incoming line cabinet 110 is hinged with enterprising Line panel 310, upper incoming line panel 310 are equipped with master switch 311, ammeter 312 and several indicator lights 313, and incoming line cabinet 110 is just Lower inlet wire panel 320 is hinged on the downside of face, lower inlet wire panel 320 is equipped with observation window 321, and the front upside of capacitor box 120 is hinged There is upper electric capacity panel 410, upper electric capacity panel 410 is equipped with control table 411, ammeter 312 and switch fuse 412, capacitor box 120 Positive downside is hinged with lower electric capacity panel 420, and lower electric capacity panel 420 is equipped with several buttons 421, the incoming line cabinet 110, capacitor 120, two outgoing line cabinets 130 of cabinet are arranged successively and mutually isolated.

By installing the electrical component of needs in advance on the panel of each function counter, to facilitate later period electrical wiring, improve Packaging efficiency.

The cabinet door 600 is made of two symmetrical door-plates 610, and each door-plate 610 is equipped with observation window 321 and solidus Folder.When maintenance personal safeguards, it can carry out checking the break-make situation of electrical component roughly through the observation window 321 on door-plate 610, Actual test and wiring work can be carried out by opening cabinet door 600, maintenance personal can be facilitated temporarily to hang electric wire by wire fixing clamp, Convenient for operation.Meanwhile when in order to overhaul can Simultaneous identification cabinet concrete model, nameplate can also be set in cabinet door 600.
