Description
Technical field
The present invention relates to dispatching electro-technical fields, and in particular to a kind of three-phase load unbalance comprehensive distribution box.
Background technology
Distribution box be by electrical wiring requirement by switchgear, measuring instrumentss, protection is electrical and ancillary equipment is assembled in envelope
Close or semiclosed metal safe in and constitute power distribution equipment, be widely used with power station, distribution substation, electric substation, industrial and mineral build field
Institute etc..
Population is continuously increased now, and house starts to increase, and then electricity demand increases, and every household all uses better height
Electric appliance, in some high buildings be often several users ammeter concentrate at one, increase the equipment such as transformer, storage battery.So
And instantly population increase, housing need speed it is fast, the demand of electricity consumption is also big therewith, and original transmission line of electricity does not change, cause
Single-phase load is set to increase, three-phase current unbalance causes entire electric power netting safe running hidden danger occur.
Therefore it needs to provide a kind of distribution box that can overcome three-phase load unbalance electric current, has corresponding three-phase negative at present
Lotus unbalancing device, but now for placement of the device in regular distribution case connected or weld using screw thread
It connects, but distribution box is generally an exposure in air, being threadedly coupled can contact with air and be got rusty easily because of long-time, if
Midway have several times repair if be easy for causing to be screwed not fastening, and weld then be easy because be chronically exposed in air and
Weld corrosion is set to loosen, the connection for also leading to three-phase load unbalance device and distribution box body is insecure.
Invention content
The present invention for the above technical problems, provides a kind of three-phase load unbalance comprehensive distribution box, to solve
Existing distribution box be chronically exposed in air be easy to cause three-phase load unbalance device connect with distribution box body it is unstable
Problem.
In order to solve the above technical problem, the present invention provides following basic technology schemes：A kind of three-phase load unbalance is comprehensive
Distribution box, including babinet are closed, the babinet includes internal box and outer case, and outer case is equipped with outer door body, and internal box is equipped with
Interior door body；Gap is reserved between the internal box and outer case, the bottom of outer case is equipped with sliding slot, and sliding slot extends to outer door body
The bottom at place, internal box is equipped with sliding rail, and sliding rail is slidably connected with sliding slot and connects；The internal box is internally provided with column, column it is upper
Lower both ends are rotatably connected on the top of internal box and the bottom of internal box respectively, are fixedly connected on the column and are useful for placement three
The bracket of phase load unbalancing device, the bracket include supporting support, and the lower end of supporting support is connected with bottom bracket, support
The upper end of holder is connected with top-support；The bottom bracket includes lifting plate and connecting up in the baffle for lifting edges of boards edge.
The operation principle of the present invention：When distribution box is packed into three-phase load unbalance device, outer door body is opened, because of outer container
It is slidably connected by sliding slot and sliding rail between body and internal box, sliding slot extends at outer door body, it is possible to internal box is pulled, it will
Internal box slides at outer door body.Then door body in opening, three-phase load unbalance device is mounted on bracket, keeps three-phase negative
The bottom of lotus unbalancing device is placed on lift plate, and the baffle that supporting support is connected with lift edges of boards edge limits three-phase load unbalance
The shaking of device.The bottom bracket collective effect that the top-support of the upper end connection of supporting support is connect with supporting support lower end,
The position for the limitation three-phase load unbalance device that can stablize, avoids the shaking of three-phase load unbalance device and topples over, into
And the setting for keeping three-phase load unbalance device firm is in internal box.
By the way that outer case and internal box is arranged, circulation of the air in interior box house is reduced in this way, and then is reduced and be located at
The amount of the air of three-phase load unbalance device contact in internal box.Furthermore because three-phase load unbalance device is being run
During will produce heat, then heat is dispersed by internal box in gap, is that air themperature in gap increases, is reduced
The humidity of this partial air, and then reduce the possibility that each component gets rusty inside distribution box.
Beneficial effects of the present invention are：This programme is set by the internal box and outer case that are slidably connected in interior box house
The bracket of placement location three-phase load unbalance device can easily be filled three-phase load unbalance by sliding internal box in this way
For placement location on bracket, the structure of bracket can limit the position of three-phase load unbalance device, and firm fixed column three-phase is negative
The position of lotus unbalancing device avoids shaking and topple over, and repair is facilitated to replace three-phase load unbalance device.Internal box and
Gap between outer case can accumulate heat, reduce the humidity of air in gap, reduce air and the circulation inside internal box,
And then reduce the possibility that each component gets rusty.
It is the optimization to basic technology scheme below：
Prioritization scheme one：The lift plate is equipped with tongue-and-groove, and the extending direction of the tongue-and-groove is identical as the lift length direction of plate.
This prioritization scheme can further limit the position of three-phase load unbalance device, before three-phase load unbalance device is installed,
Be set to the corresponding tenon item of tongue-and-groove in its bottom, tenon item is slidably connected in tongue-and-groove, such tongue-and-groove can card column tenon item, in turn
Preferably fixed three-phase load unbalance device.
Prioritization scheme two is based on prioritization scheme one：The internal box is equipped with air vent and exhaust fan, in the outer case
Equipped with exhaust outlet and air intake vent.Because three-phase load unbalance device will produce heat in use, in order to avoid load
The heat generated when excessive is excessively high and generates security risk, is rapidly discharged to hot-air in gap by exhaust fan, and phase
The air of low temperature is added to from air vent in internal box.The air intake vent and exhaust outlet of outer case carry out the replacement of hot and cold air.
Prioritization scheme three is based on prioritization scheme two：The outer wall of the outer case be equipped with hide dirt canopy, the screening dirt canopy be located at into
The top in air port.In order to avoid the dust carried secretly in air is largely entered by air intake vent in outer case, it is quiet to reduce generation
The possibility of electricity, in the top of air intake vent, setting hides dirt canopy, and hiding dirt canopy can be with the entrance of shield portions dust.
Prioritization scheme four is based on prioritization scheme three：The Air Filter for filtering dust is equipped at the air intake vent.It is such
Setting can stop most dust by Air Filter, be further reduced into the dust in internal box.
Prioritization scheme five is based on prioritization scheme four：The periphery of the internal box is provided with ventilation duct, the ventilation duct
Air inlet be located at outside outer case and be connected with air-cooler, the air outlet of ventilation duct is located at the outside of outer case.In ventilation duct
It is passed through cold wind, can more quickly reduce the temperature in internal box, use is safer.
