Description
Technical field
The utility model belongs to a kind of 10kV high-voltage connecting electronic box, relates to the improvement of this high-voltage connecting electronic box enclosed construction, improves its sealing property, to meet the fail safe of electricity consumption.
Background technology
The high-voltage connecting electronic box is widely used in various occasions, for example port and pier, construction site, petrochemical plant etc., need to seal implementing in its case, at present, people are common to be done the genealogy of law and adopts the gap between sealing ring sealing case lid and casing, to prevent water etc., enters in case.But the high-voltage connecting electronic box polyphyly in above-mentioned environment is exposed to the external world, stand the even water logging of flood of strong wind and heavy rain, in this case, existing high-voltage connecting electronic box is difficult to meet the requirement of technical sealing, causes regularly occurring electric short trouble.
Summary of the invention
The purpose of this utility model is that a kind of 10kV high-voltage connecting electronic box will be provided, this 10kV high-voltage connecting electronic box has proposed a kind of enclosed construction, with immersion and the impact that tackles heavy rain, especially to existing, occur slightly to seep water and taked the protective treatment measure, to improve its inner sealing property.
The purpose of this utility model is realized by following scheme:
A kind of 10kV high-voltage connecting electronic box, comprise casing and case lid, is characterized in: the joint at wall box and casing edge is inwardly along level to extending to form inside edge, inside edge again upwards vertical stretching form straight wall, straight wall outwards stretches out and forms upper edge as level again; The casing edge is inlaid with bimodal sealing ring; Case lid is stepped, and the joint of case lid downstairs and case lid sidewall inwardly connects edge along level in extending to form; Case lid is placed on casing, by the case lid downstairs be pressed on sealing ring and with the casing sealing, and case lid in connect along being attached on the inside edge of casing, on case lid, ladder is attached on the upper edge of casing.
Like this, can lock screw at case lid downstairs and casing edge, make case lid downstairs and casing edge approaching, make the sealing ring strain and seal with the external world, reach sealing, in addition, inside edge by casing, straight wall, upper edge, case lid and in connect along having formed again a chamber, this chamber can play the effect that cushions its impulse force and accumulate to water or the dust leaked into, especially in, connect along with the laminating of inside edge, playing to the water that may leak into etc. the effect of guiding, water is directed to and flows to straight wall, to reduce its impulse force and to rush at top, on case lid, another layer of enclosed construction constructed in the laminating of ladder and casing upper edge, and because this structure is positioned at top, the water leaked into is difficult for spattering to this top and can flow directly into box house.
This 10kV high-voltage connecting electronic box has better sealing property, can stand heavy rain or flood and constantly soak and impact, just in case produce slight infiltration, the effect that can play buffering and accumulate the water leaked into, stop it directly to enter in case simultaneously, to electricity, can play the effect of strengthening protection.
Be preferably, in such scheme, the wire inlet/outlet hole sealing device is equipped with in the cable incoming-outgoing wire hole, and the wire inlet/outlet hole sealing device comprises pedestal, sealing ring and plug screw, wherein, pedestal cavity front portion is rendered as coniform, pedestal cavity rear portion is cylindric, and the pedestal rear portion is formed with screw thread in the surrounding of cylindrical cavity, and plug screw central authorities have the perforate of passing through for cable, sealing ring is placed in the pedestal cavity, and plug screw is threaded onto pedestal and is acted on sealing ring by the plug screw leading section.
Like this, the deformation of sealing ring pressurized, be squeezed in pedestal cavity front portion, can play the effect of sealing more to entering in case and connecting outside cable in case.
Thus obtained 10kV high-voltage connecting electronic box, after tested, its sealing effectiveness is higher, can reach the above rank of IP67.
