Embodiment
Below in conjunction with accompanying drawing and concrete execution mode, the utility model will be further described.
According to advantage of the present utility model see Fig. 2-Fig. 5, provide a kind of switch cubicle, comprise housing 101 and cabinet door 102, the inside of described housing 101 is provided with fuse 104, on-load switch 116, isolating switch 103, operating mechanism 105; In the application, isolating switch preferentially selects tri-station isolating switch.So-called three stations refer to three service positions: the closing position that 1 isolated switch main fracture is connected, the isolated location that 2 main fractures separate, the earthing position of 3 ground side.Three-station is exactly the function incorporating isolating switch and earthed switch in fact, and come by a cutter, so just mechanical latching can be realized, prevent major loop charged conjunction ground cutter, because one a position, and can only not resemble traditional isolating switch cutter, operator is operator, ground cutter is ground cutter, just may go out misoperation between two cuttves.Use tri-station isolating switch, avoid the possibility of misoperation.
Described isolating switch, on-load switch 116 are connected successively with fuse, and described operating mechanism is connected with on-load switch and isolating switch, and described on-load switch is fixed sealing type on-load switch, and described isolating switch is fixed sealing type isolating switch.
The fixed sealing material of fuse and described isolating switch is preferably epoxy resin, and the macromolecular compound containing epoxide group in all molecular structures is referred to as epoxy resin.Epoxy resin after solidification has good physics, chemical property, and it has excellent adhesive strength to the surface of metal and nonmetallic materials, and dielectric property are good, set shrinkage is little, product size good stability, and hardness is high, pliability is better, to alkali and most of solvent-stable.
Isolating switch is often preferably all independently built mutually and is integrated.The automatic gel process of APG specifically can be adopted independently to build, and the automatic gel process of APG is existing technique, repeats no more herein.Adopt the structural reliability of independently building high, stop phase fault.
The housing of described switch cubicle and cabinet door are preferably sealing, concrete, and the cabinet door of switch cubicle can install sealing strip 107.Inside switch cabinet can be entered by effectively anti-sealing like this.
The housing of switch cubicle needs inlet wire, therefore entrance hole is had, entrance hole is existing, repeat no more herein, the entrance hole of the application is also provided with water-tight device, water-tight device can use existing device, in the application, water-tight device is lock-on connection 108, described lock-on connection comprises nut 109, clamp jaw 110, main body 111, packing ring 112, nut 114 and cushion rubber 113, described clamp jaw is positioned at described nut and main body, described nut is connected with described main body one end, described nut is connected with the other end of affiliated main body, packing ring and cushion rubber is had between described nut and described main body, cushion rubber is had between described nut and described clamp jaw, cushion rubber is had between described nut and described main body.In the application, original lock-on connection is installed the cushion rubber being used for water-tight, enclosure interior can have been entered by entrance hole and conductor spacing by effectively anti-sealing.
After being sealed by switch cubicle, the switch cubicle heat loss that is in operation is comparatively slow, and the housing of described switch cubicle is for this reason provided with aluminum pipe 118, and there is screw thread at the two ends of described aluminum pipe.Aluminum pipe can be threaded connection liquid cooling apparatus (such as oil cooling cooling system) during use, by the circulation of liquid in aluminum pipe, heat be taken away, be conducive to switch cubicle heat radiation.
In the application, the junction of on-load switch and described operating mechanism is preferably socketed with bellows 117, concrete on-load switch and described operating mechanism can be connected by connecting rod, on connecting rod, cover has bellows, on-load switch is connected real existing connected mode with described operating mechanism connecting rod, repeats no more herein.Can by sylphon seal during use, even if there is a small amount of water to enter inside switch cabinet like this, also be not easy to run on-load switch and operating mechanism immediately to have an impact, improve the fail safe that switch cubicle runs, certainly other places also can seal, and such as isolating switch and manipulator component sealing ring seal.
Prove by experiment, the switch cubicle that the application provides can run in the short time in immersion, and the good words of seal receptacle even can be soaked operation more than one week, when especially using for the rescue of floods, can reduce danger, or provides the power supply of longer time for rescue.
In the application, the protective device of switch cubicle can use passive microcomputer protecting device, realizes defencive function when secondary current is more than or equal to threshold value.
Certainly, as shown in Fig. 6 A, Fig. 6 B, the solid all insulation combined electrical apparatus switch cubicle that the utility model provides can also comprise the existing structure of electrification display 119, action button 120, cabinet door lock 121, observation window 122, handle 123 etc.If certain observation window sealing, can be glass or transparent plastic sheet sealing.
It should be noted, above-described embodiment is described the utility model instead of limits the utility model, and those skilled in the art can design alternative embodiment when not departing from the scope of claims.In the claims, any reference symbol between bracket should be configured to limitations on claims.Word " comprises " not to be got rid of existence and does not arrange element in the claims or step.Word "a" or "an" before being positioned at element is not got rid of and be there is multiple such element.The utility model can by means of including the hardware of some different elements and realizing by means of the computer of suitably programming.In the unit claim listing some devices, several in these devices can be carry out imbody by same hardware branch.Word first, second and third-class use do not represent any order.Can be title by these word explanations.
