Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides a 10kV explosion-proof type high tension cable branch box, includes the box, and the box top is provided with the through-hole, is provided with explosion-proof equipment on the through-hole, and explosion-proof equipment includes inside cavity and upper and lower open-ended round platform, and swing joint has shield 52 above round platform 51, and round platform 51 top round is equipped with a plurality of recess 53, shield 52 with be provided with on the corresponding position of recess 53 with the cylindricality section of thick bamboo 54 of recess 53 looks adaptation, with the corresponding position fixedly connected with spring 55 of recess 53 on shield 52, the one end of spring 55 is fixed the bottom of cylindricality section of thick bamboo 54, the bottom at recess 53 is fixed to the other end, shield 52 the shape with the shape of round platform 51 is the same, makes shield 52 can cover. The circular truncated cone 51 and the dust cover 52 are matched with each other through the groove 53 and the cylindrical barrel 54 under the normal condition, namely, the cylindrical barrel 54 is inserted into the groove 53, and the spring 55 is in a compressed state.

In order to avoid that the dust cover 52 cannot reset after pressure relief is finished after being jacked up by explosive gas in the box body, a plurality of guide posts 56 are welded on the outer inclined surface of the circular truncated cone 51, and round holes for the guide posts 56 to pass through are formed in the positions, corresponding to the guide posts 56, of the dust cover 52. The dust cap 52 is allowed to move only up and down along the guide post 56, ensuring that the dust cap 52 will positively enable the cylindrical barrel 54 to drop into the recess 53 during the reset process.

A cooling chamber is arranged on one side of the box body, and a refrigerating mechanism is arranged on the inner side wall of the cooling chamber. Refrigerating mechanism includes connecting plate and a plurality of sheetmetals 3 of parallel arrangement on connecting plate 7, is provided with the bar hole on the lateral wall of cooling room, and refrigerating mechanism injects through the bar hole in the cooling room. Install refrigeration piece 2 on the connecting plate 7, 2 electric connection of refrigeration piece have the controller, controller electric connection has the battery, battery electric connection has solar cell panel 1, controller electric connection has thermodetector 4.

Be provided with receiver 6 that the top can be opened on the box inner wall, can set up a plurality ofly according to actual conditions, the equipartition has a plurality of gas pocket on the lateral wall of receiver 6, can deposit the silica gel drier in the receiver 6, reduces the incasement wet condition, avoids taking place the short circuit.

When the incasement temperature was too high, thermodetector 4 detected high temperature dangerous, and the controller makes the work of refrigeration piece 2 at once, and the low temperature passes through sheetmetal 3 conduction to the cooling chamber in, reduces the indoor temperature of cooling, because the cooling chamber is independent of the box inside, has avoided if 2 electric leakages of refrigeration pieces, and sheetmetal 3 directly is in conducting state, probably burns out the condition of equipment. If the interior of the branch box is in a high-temperature and high-pressure state when the interior of the branch box explodes, the dust cover 52 is easily jacked open under the action of air pressure, and air in the box can quickly escape out of the box, so that the danger caused by explosion is reduced. Meanwhile, the temperature in the box body is reduced through the refrigerating mechanism, so that the temperature in the box body is reduced. When the air pressure inside and outside is balanced, the dust cap 52 automatically cooperates with the circular truncated cone 51 under the guide of the guide post 56 due to the self gravity, and the original shape is recovered.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
