Description
Technical field
The invention relates to a kind of power supply box, particularly the special maintenance power box of a kind of Novel transformer substation.
Background technology
As everyone knows, in the maintenance repair of transformer station, maintenance work, often can use station power supply box as external power supply feed point.And station power supply box has inseparable electrical communication with transformer station's AC low-tension system, and due to outdoor, if protect the bad safe operation that has influence on possibly whole transformer station.And the maintenance power box that most of transformer station is used is connecting after maintenance cable, capital causes chamber door to close, as run into sleety weather or toy creeps into maintenance power box, all may cause the short circuit of maintenance power box back panel wiring or ground connection, cause very large hidden danger to the safe operation of transformer station.
Summary of the invention
The problem that the invention will solve is to provide a kind of good airproof performance, easy to install, strong and have a special maintenance power box of Novel transformer substation of humidity control to workload-adaptability.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: the special maintenance power box of a kind of Novel transformer substation, comprise the maintenance power box body being fixed on base, and this body divides upper and lower two-layer and separates described dividing plate perforate with dividing plate; Chamfering between top blind flange and horizontal plane is acute angle; Body is provided with Qian Zhumen, front secondary door and back door; On back door, be provided with heating plate; Body interior is provided with pcb board, is integrated with trip protection device and air circuit on this pcb board, also comprises socket and connection bolt.
Further, at dividing plate tapping mounting sleeve.Dividing plate carries out perforate according to the diameter of the conventional cable of difference, and the sleeve pipe of PVC material is installed at tapping, not only can prevent dividing plate incised wound cable, and has played the effect of attached cable.
Further, top blind flange becomes 15 degree chamferings with horizontal plane, can prevent top ponding and casing infiltration.
Further, described Qian Zhumen, front secondary door and back door are three and can 180 spend the hermatic door of opening.On front secondary door, be provided with window, on window, have multiple holes, and sagging catch is arranged in hole on corresponding window.
Front and back arrange 3 doors altogether, facilitate the installation of maintenance power box.When normal use, open front main door and can check that whether maintenance power box internal circuit is normal; On front secondary door, window is set, on window, commonly use cable size perforate according to difference, and sagging catch is arranged in hole on corresponding window, only select the window in aperture just can open, do not select the window catch in aperture, gravitate, naturally droop and close, design, on the one hand, has reached the object of anti-toy like this; On the other hand, the perforate of the perforate on window and levels dividing plate can cooperatively interact, attached cable.Front secondary door, after load line wiring, can normally be closed, and has effectively guaranteed the sealing of maintenance power box.Back door is provided with silicon heating plate, the in the situation that of wet weather, opens, avoided maintenance power box inner air too humidity cause short circuit.Connection bolt adopts with the copper screw of insulator cap, on insulator cap with antiskid thread.Back panel wiring bolt adopts with the copper screw of insulator cap and replaces in the past exposed screw to carry out the fixing of load line, and handled easily is safer, prevents the mechanical damage of connection bolt.
Advantage and good effect that the invention has are: adopt technique scheme, the invention is with respect to the progress of maintenance power box in the past:
1. sealing is good---all salable closing of front/rear door after wiring, and the line of cable all has the aperture adapting, and reached like this requirement of anti-toy in Southern Power Grid Company " electric power safety working regulation (power transformation part) ".
2. easy to install---the maintenance power box body of the invention adopts hierarchical design, and layering is installed, and makes installation process more quick, and it is more clear to check and accept; All can wide-angle open at Qian Zhumen, front secondary door, back door, is convenient to laying of cable; Cable punching hole enters power supply box, automatically fixing, has removed the trouble of attached cable trend in the past from; Loaded cable is fixed on connection bolt by the copper screw with insulator cap, and on insulator cap, with the antiskid thread that strengthens frictional force, in the situation that assurance is safe, staff wears insulating gloves and can operate, and has removed from and has needed the trouble fixing with spanner in the past.
3. strong to workload-adaptability---than trip protection device in the past; the trip protection device that this power supply box adopts; operating current is adjustable; can adjust flexibly operating current for different loads; strengthen the adaptability of power supply box; also improve the level of protection to electrical equipment, reached the regulation about " branch switch of maintenance electrical source of power case all should install the RCD (earth leakage protective device) adapting additional " in Southern Power Grid Company " electric power safety working regulation (power transformation part) ".
4. good humidity control---maintenance power box back door is provided with silicon heating plate, the in the situation that of wet weather, open, that power supply box interior humidity horizontal dimension is held in the humidity level about " place power supply box, terminal box " of regulation in Southern Power Grid Company " electric power safety working regulation (power transformation part) ", avoided maintenance power box inner air too humidity cause short circuit.

Embodiment
In conjunction with the accompanying drawings and embodiments the technical scheme of the invention is elaborated.
As shown in Fig. 1,2 or 3, the special maintenance power box of a kind of Novel transformer substation, comprises and utilizes angle steel 3 to be fixed in the maintenance power box body on base, and this body divides upper and lower two-layer and separates with dividing plate, and described dividing plate perforate, at dividing plate tapping mounting sleeve; Top blind flange 1 becomes 15 degree chamferings with horizontal plane; Can prevent top ponding and casing infiltration.Body is provided with 5 three, front main door 2, front secondary door 4 and back door and can 180 spends the hermatic door of opening; On front secondary door 4, be provided with window, on window, have multiple holes 7, and sagging catch 6 is arranged in hole 7 on corresponding window.On back door 5, be provided with heating plate; Body interior is provided with pcb board, is integrated with trip protection device, air circuit, socket and connection bolt on this pcb board.The trip protection device that internal circuit adopts can freely arrange trip rating, has greatly improved the compatibility to various electric equipments.In addition, back panel wiring bolt adopts with the copper screw of insulator cap and replaces in the past exposed screw to carry out the fixing of load line, and handled easily is safer, prevents on the mechanical damage of connection bolt and the insulator cap of connection bolt with antiskid thread.In the situation that assurance is safe, staff wears insulating gloves and can operate, and has removed from and has needed the trouble fixing with spanner in the past.
