A kind of distribution box with dehydrating unit
Technical field
The utility model relates to field of machining, and more particularly, it relates to a kind of distribution box with dehydrating unit.
Background technology
Humidity is the inherent characteristic of the underground space, the thermal and humidity environment of underground works is very large to the reliability effect of electric equipment, for the electric equipment used under high humidity atmosphere, adopt carries out damp-proof treatment to components and parts itself more both at home and abroad at present, improve the barrier propterty of components and parts, but, adopt damp-heat type components and parts product cost higher, so except except the particular application such as boats and ships, nearly all adopt regular tap device, entirety protection against the tide is carried out to the distribution box that equipment is concentrated, as the relative humidity taking the methods such as Resistant heating oven dry to reduce box house, but this moistureproof mode is after equipment is out of service, box house relative humidity increases again, serious meeting causes moisture condensation, accelerate the corrosion of electric equipment.
In distribution box, electric device is more concentrated, be afraid of most moisture damage, in order to remove the moisture of power transformation box, therefore generally need to place drier, but the chamber door of distribution box is often opened, when opening, a large amount of malaria enters, and drier will soon be made to lose efficacy, and causes distribution box interior humidity when normal work very high.
In order to prevent dry rapid failure, number of patent application 201320056859.5 1 kinds effectively reduces the distribution box of interior humidity, comprise casing and the chamber door being installed on described box opening, bottom in described casing is installed with desiccant box, silica-gel desiccant is loaded with in described desiccant box, and the box mouth of described desiccant box utilizes slot to be slidably fitted with removable cover, the rear portion of described removable cover utilizes extension spring to be connected on described casing, and the front portion of described removable cover utilizes rigidity rope to be connected on chamber door.The utility model chamber door open a large amount of malaria enter time, drier can be closed, be not easy to lose efficacy, therefore substantially prolongs useful life, effectively reduce distribution box interior humidity when normal work, but there is following shortcoming in this application file: 1, removable cover is pullled by rigidity rope to slide, desiccant box is made to carry out opening or closing, chamber door is in the opening process of side, rigidity rope tension direction can become once angle with removable cover, and this angle can be increasing, make some skews can occur in removable cover sliding process, removable cover is made easily to be stuck on the slot of box mouth, cannot normally use,
2, because desiccant box is the bottom be fixed in casing, open chamber door when entering in casing, the rigidity rope on removable cover is in exceptionally straight state, and rigidity rope easily stumbles operating personnel, is inconvenient to use.
