Abstract
The utility model provides an anti-explosion middle junction box between an electrical device and a power distribution box and can effectively shorten the length of a device end cable and facilitate transportation and maintenance. The anti-explosion middle junction box comprises a box body and binding posts, wherein the binding posts are fixed between the box bottom, and insulators are installed between the binding posts and the box bottom and erected in a cavity of the box body. The lateral end of the bottom of the box body is provided with a wire inlet hole and a wire outlet hole. Each binding post is provided with a conducting cable clamp, and two binding posts form a pair. The cable clamps on each pair of binding posts are electrically connected through connecting pieces. Sealing parts are arranged in the wire inlet hole and the wire outlet hole. When the electrical device is dismantled and maintained, a cable can be dismantled from the position of the anti-explosion middle junction box, the situation that the cable and the electrical device are maintained simultaneously is avoided, the length of the cable carried by the device is effectively shortened, the working intensity is reduced remarkably, and the work efficiency is improved. The extruding and damage rate of the cable is reduced, and the middle junction box has good anti-explosion performance and can be applied to a specific place.
Description
Technical field
The utility model relates to the termination of electric equipment, and the anti-explosion intermediate junction box between especially a kind of electric equipment and the distribution box can effectively reduce the equipment end cable length, convenient transportation and maintenance.
Background technology
In service in actual production, electric equipment need to overhaul and maintain termly, carry out dismounting, the connection of equipment cable.The main equipment cable is thicker, be generally the 3 phase anti-explosion cables that 2 diameters are 120mm such as 260kw fire pump cable, when carrying out overhaul of the equipments, because cable link connects in the motor the inside, can't dismantle the cable link of motor side, can only dismantle the cable link of distribution box end, cable link between electric equipment and the distribution box together be sent with electric equipment repair.This can cause the cable that is connected on the motor long, overhaul, extremely inconvenient when transporting.Offshore platform particularly, cable between its electric equipment and the distribution box reaches tens meters, over one hundred rice, because cable is longer, when dismounting, transportation, maintenance, need to twine these cables, not only working strength is large, and can increase the probability that cable squeezes wound, disrepair phenomenon, produces unnecessary economic loss.
Summary of the invention
The utility model is in order to overcome above-mentioned technical problem; anti-explosion intermediate junction box between a kind of electric equipment and the distribution box is provided, has been installed on the cable of nearly electric equipment end, effectively reduced, shorten and send the cable length of repairing the electric equipment end; the protection cable, convenient for maintaining.
The utility model is achieved in that the anti-explosion intermediate junction box between a kind of electric equipment and the distribution box comprises box body and binding post, at the bottom of each binding post is fixed on box, and box at the bottom of between insulator is housed, stand upright in the cavity of box body; The bottom portion side end of box body is provided with entrance hole and wire hole; Be provided with the strain relief clamp of conduction on each binding post, two binding posts are a pair of; Strain relief clamp on each pairs of posts conducts mutually by brace; Be equipped with seal in entrance hole and the wire hole.Binding post stands in the internal cavities of box body and with box body and insulate; Cable is received on the strain relief clamp after being entered by entrance hole, and is connected with the outlet cable by brace, and the outlet cable passes by wire hole, to guarantee the sealing in the whole cable connection procedure, is convenient to it and uses at explosion-proof area.
The beneficial effects of the utility model are: the utility model is installed on the cable of nearly electric equipment end, during the electric equipment detachable maintaining, can be from the utility model dismounting cable, avoid stube cable together to keep in repair with electric equipment, the length of effective minimizing equipment institute tape cable, significantly reduce working strength, improved operating efficiency.Reduce simultaneously equipment in dismantling, transport, overhauling, the probability that cable squeezes wound, breakage occurred.The utility model is simple in structure, and is reasonable in design, can carry out rapidly connection and the dismounting of electric equipment cable.The utility model pairs of posts and entrance hole and wire hole have all been done insulation processing, have good explosion-proof performance, can be applied to specific place.
Description of drawings
Accompanying drawing is internal structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.Referring to accompanying drawing, the anti-explosion intermediate junction box between a kind of electric equipment and the distribution box comprises box body 1 and binding post 4, at the bottom of each binding post 4 is fixed on box, and box at the bottom of between insulator is housed, stand upright in the cavity of box body 1; The bottom portion side end of box body 1 is provided with entrance hole 2 and wire hole 3; 5, two binding posts of strain relief clamp 4 that are provided with conduction on each binding post 4 are a pair of; Strain relief clamp 5 on each pairs of posts 4 conducts mutually by brace 6; Be equipped with seal in entrance hole 2 and the wire hole 3, cable is realized sealing and insulation.Lid is installed in the top of box body 1, and box body 1 is provided with mutual corresponding bolt hole 7 with the assembling edge of lid.The quantity of described entrance hole 2 and wire hole 3 is 2, and described binding post 4 arranges 6 pairs, can realize the connection of two group of 3 phase cable.During use, will be entered by entrance hole 2 from the threephase cable of distribution box, be connected on three strain relief clamps 5 on the binding post 4, the outlet cable is connected on the strain relief clamp 5 on the same pairs of posts 4, and is passed with electric equipment by wire hole 3 and to be connected.At wire hole 2, entrance hole 3 seal that seals is set; By the cooperating of lid and box body 1, can effectively guarantee the sealing of cavity between lid and the box body 1 again, make it satisfy the instructions for use of explosion-proof area.This anti-explosion terminal box is installed in device context, can effectively reduces the cable length of electric equipment end, reduce the damage probability of equipment cable.
