Description
The application is the applying date is 2015-02-05, and application number is 201510062012.1, and denomination of invention is the divisional application of the patent application of high voltage power distributing cabinet.
Technical field
The present invention relates to a kind of high voltage power distributing cabinet, belong to electrical equipment technical field.
Background technology
High voltage power distributing cabinet refers to for playing the effects such as break-make, control or protection in power system generating, transmission of electricity, distribution, electric energy conversion and consumption; electric pressure is in the electric equipment products of 3.6kV～550kV; mainly include primary cut-out, high voltage isolator and earthed switch, high voltage load switch, high pressure automatic reclosing and sectionaliser, several big classes such as high-voltage actuating mechanism, high-voltage explosion-proof power distribution equipment and high-tension switch cabinet.High-voltage switch gear manufacturing industry is the manufacturing important component part of power transmission and transforming equipment, occupies very important status in whole power industry.High voltage power distributing cabinet is often unavoidably subject to the invasion and attack of water, if water instills from the plan vertical of power distribution cabinet or is tilted into inside power distribution cabinet, the element of power distribution cabinet will be soaked in water, thus causing that electric equipment short circuit cannot be properly functioning.Instill from the plan vertical of power distribution cabinet to solve rainwater or tilt to instill, the whole body of power distribution cabinet being designed as sealing structure by prior art, although to some extent solve the waterproof problem of power distribution cabinet, but ignore the heat dissipation problem of power distribution cabinet.Also a very scabrous problem is: working as rainstorm weather, the hydrops on ground is a lot, it is easy to is entered into the inside of power distribution cabinet by the ventilating heat dissipating hole of power distribution cabinet or cabinet door gap, causes the short circuit within power distribution cabinet.
So high voltage power distributing cabinet seems to be difficult to solve for heat radiation and two problems of waterproof simultaneously, solve heat radiation and be difficult to accomplish good waterproof, and solve waterproof problem and seem to be difficult to solve heat dissipation problem.
Existing high voltage power distributing cabinet, the height of each chamber is equally high, and some components and parts height are significantly high, and some components and parts height are very low, but the height of each chamber of existing power distribution cabinet is all changeless, causes that the space availability ratio within cabinet is very low.
Summary of the invention
The technical problem to be solved in the present invention is: first, existing high voltage power distributing cabinet, and the height of each chamber is equally high, and some components and parts height are significantly high, and some components and parts height are very low, and the constant height of each chamber is constant, and the space availability ratio of whole power distribution cabinet is very low.Second, current high voltage power distributing cabinet internal temperature is high easily caused by fire, power distribution cabinet is the place that whole network system fire is occurred frequently, and power distribution cabinet internal temperature height is easier to cause component aging, reducing service life, in order to often have a lot of louvre on the cabinet of heat dissipation power distribution cabinet, but rainwater enters easily by louvre, and it is very deep that rainstorm weather carrys out interim excess surface water, and excess surface water enters into inside power distribution cabinet easily by cabinet crack between a door and its frame gap or the ventilating heat dissipating hole of power distribution cabinet.
In order to solve above technical problem, the technical solution adopted in the present invention is: high voltage power distributing cabinet, and including cabinet, cabinet front portion arranges cabinet door；The rear board of cabinet has been arranged in vertical two row screwed holes, distance between the adjacent screw holes of left and right is all equal, distance between neighbouring screwed hole is also equal, and the distance between upper and lower screwed hole is less than 5cm, and left and right adjacent screw holes is positioned at same level；
Cabinet comprises multiple lateral partitions, is removably connected by nut between lateral partitions and the rear board of cabinet, all without being connected between lateral partitions and left panel and the right panel of cabinet；
The end face of cabinet and bottom surface are respectively provided with an air inlet；
Also include temperature sensor, controller, blower fan, flexible ajutage；
Temperature sensor is arranged at inside cabinet, and the temperature signal of temperature sensor collection is input to controller, and controller controls the start and stop of blower fan；
Flexible ajutage comprises an input port and two delivery outlets, and the air outlet of blower fan connects the input port of flexible ajutage, and the delivery outlet of flexible ajutage connects the air inlet of cabinet end face and bottom surface respectively；
Also include circle to keep off the rain ceiling, barrel-shaped water-tight device；
Cabinet is arranged at the centre of barrel-shaped water-tight device, and the circle ceiling that keeps off the rain is arranged at the top of cabinet；
The circle ceiling that keeps off the rain is perpendicular to the projection on ground and covers barrel-shaped water-tight device and be perpendicular to the projection on ground；
Distance between cabinet door and the side of barrel-shaped water-tight device of cabinet is all higher than the width of cabinet door；
The bottom surface of described barrel-shaped water-tight device and side are respectively provided with water resistance；
The bottom surface of described barrel-shaped water-tight device is parallel to ground.
Further, the cabinet door of described cabinet is provided with louvre.
Further, described louvre is provided with the outward extending cover edge that keeps off the rain.
Further, described controller adopts MSP430 single-chip microcomputer.
Compared with prior art, it is an advantage of the current invention that: present invention employs special design structure, the problem effectively solving power distribution cabinet internal heat dissipating, radiating effect is very good.The power distribution cabinet with good water resistance provided by the invention, when rainstorm weather arrives, when excess surface water is a lot, enters into inside power distribution cabinet without by cabinet crack between a door and its frame gap or the ventilating heat dissipating hole of power distribution cabinet；Traditional power distribution cabinet considers necessity of waterproof, the louvre of power distribution cabinet is all not as many, due to the structure that the present invention is special, excess surface water is not likely to enter the inside of power distribution cabinet, therefore the present invention can arrange more louvre, it is more beneficial for the heat radiation of power distribution cabinet internal circuit, extends the service life of power distribution cabinet electric equipment.The circle ceiling that keeps off the rain is perpendicular to the projection on ground and covers barrel-shaped water-tight device and be perpendicular to the projection on ground, thus ensureing that the rainwater that sky falls will not fall into the inside of barrel-shaped water-tight device；Distance between cabinet door and the side of barrel-shaped water-tight device of cabinet is all higher than the width of cabinet door, thus ensureing that cabinet door can normally be opened.The space availability ratio of the high voltage power distributing cabinet of the present invention is significantly high, and the height of each chamber can at will adjust.
