Abstract
The invention discloses an electrical equipment container for preventing water dripping on the top. A water collecting board is installed below the top of the container, and the cavity of the container is divided into an upper part and a lower part. A plurality of water guide grooves next to each other in sequence are arranged above the water collecting board, and at least one opening end of each water guide groove is arranged at the edge of the water collecting board. A water drainage gap is formed between the opening end of each water guide groove and the container and the top between two adjacent water guide grooves is provided with vent holes. In the invention, the water collecting board is used for collecting water droplets falling from the top of the container, so that the water droplets are prevented from falling on equipment units or electrical insulating parts. Thus, the service life of the electrical equipment can be prolonged, and the operational safety and reliability performance of the electrical equipment is improved.
Description
Technical field
The present invention relates to electrical equipment container, but a kind of electrical equipment container of preventing water dripping on top specifically.
Background technology
The mechanism case of outdoor converting equipment and terminal box are installed in the metal enclosed container; Produce condensate owing to be everlasting when influenced by ambient air temperature and wetness in the container; Condensing water droplet causes metal parts corrosion and aqueous corrosion in mechanism part and causes that the mechanical part wear extent is big and malfunctioning; Particularly drop on the low-voltage controling appliance and cause misoperation or short trouble; Cause insulating element insulation decline simultaneously and whole equipment can't normally be moved, use to equipment to bring about great losses, particularly cause power equipment malfunction or tripping to cause more serious accident.In order to prevent this from occurring, the bottom in electrical equipment container installs the dehumidifying heater additional usually, prevents that through heating humid air from condensing at the top.Yet; Humid air is heated and rises and most of humid air is discharged by the container side steam vent; But still some moist air stream concentrates at the top of container, and former thereby make moisture condensation knot water because of the top material temperature difference, water droplet drops on parts or the insulating element; Still can cause parts corrosion or aqueous corrosion, and the problem of electric terminal short circuit or decreasing insulating.
Summary of the invention
The objective of the invention is to the problems referred to above, a kind of electrical equipment container of preventing water dripping on top is provided, can effectively prevent to prolong the electric equipment life-span and improve the safety and reliability that electric equipment moves on the electric equipment in following of top condensate to the container.
The technical scheme that the present invention solves the problems of the technologies described above is: water collection sheet is housed below container top; Container intracavity is divided into two parts up and down; Said water collection sheet top is provided with several adjacent successively water guide grooves; Each water guide groove has at least an openend to be located at the water collection sheet edge, and water collection sheet is provided with drainage gap between the openend of each water guide groove and container side wall, and the top between the adjacent water guide groove has air vent hole.The humid air that rises can get into upper space along the air vent hole on the water collection sheet; And the container top condensation water is dropped on the water collection sheet and fall into the water guide groove, and the water droplet that falls in the water guide groove can flow to the container bottom discharge or receive thermal evaporation once more along container side wall.Because the container top condensate is collected and can not dripped on the electric equipment of below by water collection sheet, thereby avoids being dropped on equipment unit or the electric insulation spare.
A preferred version of the present invention is: said water guide groove laterally arranges.The water collection sheet of this structure is made simpler, and draining is convenient.
To the water collection sheet that the water guide groove laterally arranges, water collection sheet is provided with to water guide slot opening end lopsidedness in container, more helps draining.
The water droplet that the present invention adopts water collection sheet collection container top to fall, thus avoid being dropped on equipment unit or the electric insulation spare, can prolong electric equipment useful life, improve the safety and reliability of electric equipment operation.In addition, water collection sheet can adopt plastics or composite fibre materials to process, and receives variations in temperature littler than metal, is difficult for making moisture condensation knot water, and processing and install very convenient.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 be among Fig. 1 container along A-A line cutaway view.
Embodiment
As depicted in figs. 1 and 2; Electrical equipment container of the present invention is made up of sidewall 3, case top 4 and base 1; Water collection sheet 5 is located at case and pushes up 4 bottoms; Container 3 inner chambers are divided into upper space 6 and lower space 8, and electric equipment (among the figure draw in the end) and dehumidifying heater 2 are located in the container lower space 8, and the container bottom is provided with the air inlet 7 and exhaust outlet 9 that communicates with external container.Water guide groove 51 on the water collection sheet 5 laterally arranges; Each water guide groove 51 cross section is V-shaped, and water guide groove 51 two ends are openend in this example, and water collection sheet 5 is obliquely installed in container to water guide groove 51 1 side opening ends; Between the lower end of each water guide groove 51 and the sidewall 3 drainage gap 10 is arranged; Top 52 between adjacent water guide groove has a plurality of air vent holes 53, and the width of each air vent hole 53 should not surpass 5mm, falls into the below with the water droplet that reduces case top 4 drippages by air vent hole.
Its operation principle is following: the humid air of rising gets into upper space 6 along the air vent hole on the water collection sheet 5 53; And, case top 4 drops on the water collection sheet 5 after condensing into water droplet; And fall into water guide groove 51; Flow out by drainage gap 10 along water guide groove 51, flow to container bottom along container 3 sidewalls and discharge or receive once more thermal evaporation.Because air vent hole 53 is in the extreme higher position of adjacent two water guide grooves 51, drip to the possibility of following side space 8 minimum by air vent hole 53 places.And water collection sheet 5 is located in the container, and upper and lower temperature difference is little, and humid air is difficult for below water collection sheet, condensing.
Water guide groove on the water collection sheet of the present invention distributes and is not limited to the form that present embodiment provides, and can adopt the shape of radiation around the mind-set therefrom or spiral-shaped, also can take other convenient the water of collecting to be introduced into the shape that is fallen by the container either side.
