Abstract
The utility model relates to a safety device for an anti-theft anti-explosive high-voltage fuse, which is a safety device for a high-voltage fuse mainly used on a transformer. The utility model is mainly composed of an anti-theft anti-explosive high-voltage fuse and a purpose-made operating lever. The top end of a wire-connecting press cover is connected with the transformer, and the upper part of a porcelain insulator is connected and sealed by a sealing gasket and a screw. The utility model not only has the functions of theft proofing and explosion proofing, but also can guard against adverse environment such as storms, blazing sun, high temperature, etc. The purpose-made operating lever can further prevent the operation of a non-staff, and the normal and safe operation of the transformer can be further guaranteed. The utility model is a mandatory safety device of an outdoor transformer.
Description
The utility model is kind of improved safeties that are mainly used in the high-tension fuse on the transformer, it can not only be antitheft explosion-proof, can also prevent bad weathers such as storm and burning sun high temperature, the action bars of special adapted particularly advances an operation that has prevented the inoperative personnel, has guaranteed the operate as normal of transformer.
The normal still Vintage Product of fuse switch that uses early can not adapt to field work the sixth of the twelve Earthly Branches and use on the current social, be easy to stolen, again can not antitheft, explosion-proof, anti-storm etc. adverse circumstances, usually have a strong impact on normal production work.
The purpose of this utility model provide a kind of improved both can be antitheft explosion-proof, can prevent again storm and burning sun high temperature high-tension fuse one the cover safeties.
The utility model is to realize like this, mainly form a covering device by antitheft explosion-proof high-tension fuse and special action bars, this high-tension fuse is bound up on the transformer by fixed support, special action bars is arranged again, be difficult for stolen, relatively insure safety, this protective tube assembly is contained in the special ceramic insulator that can be antitheft, explosion-proof, when needs stop the transformer operation, put one by special action bars and draw the protective tube assembly just, when reasons such as transformer overloads, when blown fuse need be changed, also put once pushing away and to connect device with this action bars.
This covering device, move no noise, does not generate heat than original Vintage Product superior performance in when operation, and security personnel's insurance economize on electricity again can be antitheft, explosion-proof, prevent storm, prevent high temperature burning sun etc., is the safeties of the indispensability of outdoor transformer.
Further specify below in conjunction with accompanying drawing.Fig. 1 is the assembly structure schematic diagram of this covering device, and Fig. 2 is the structural representation of special action bars, and Fig. 3 is the another kind of schematic diagram that this kind high-tension fuse is connected with action bars.As shown in Figure 1, the top of wiring gland (1) is connected on the circuit of transformer, ceramic insulator (4) top is connected sealing by sealing gasket (3) with screw (2), protective tube lid (6) connection spring (5) is enclosed within fuse overcoat (8) and locates, to guarantee the reliable contact of fuse (9), the base (11) of band draw-in groove is equipped with in ceramic insulator (4) bottom, between base (11) and spring (5), be connected the protective tube assembly, the collet of protective tube assembly (10) is connected with base (11), and the formation path, base (11) below attended operation bar (15); Have draw-in groove more than two at base (11), so that the jaw cover of action bars (15) is entered, collet (10) and base (11) are connected and fixed by screw (12) and latch (13); When needs stop the transformer operation, base (10) with in this special action bars (15) insertion protective tube assembly rotates an angle a little, can unload protective tube, if fortuitous events such as transformer overload, when blown fuse need be changed, also hold up the protective tube assembly part, insert in the draw-in groove of base (11) with this action bars, rotate, base (11) is just held protective tube, can connect circuit, and transformer is normally moved.This action bars resembles a key, is used for loading onto or unloading protective tube, prevents that protective tube is stolen, the serious consequence that cause power failure, stops production; On insulator (4), have downward-sloping steam vent (14) in addition, so that the hyperbar that produces during blown fuse in time discharges, prevent the high pressure blast, steam vent (14) top of insulator (4) has the insulator of outstanding umbrella shape lid to block, top seals again, has realized security purposes such as antitheft, explosion-proof anti-storm, burning sun high temperature.
As shown in Figure 2, the bar head of special supporting action bars (15) is mainly formed with upper boom head fork (16) by two, be the best by what three bar heads forks (16) were formed, operation club head bottom is connected and fixed by screw (17) and insulating bar (18), insulating bar (18) lower end is connected with adapter sleeve (19), and the length of adapter sleeve is just determined with needing by easy to use.
As shown in Figure 3, the collet of former Fig. 1 (10) and base (11) or be adapted as collet (20) and base (21) is connected and fixed by screw (25) and insulator (4), chucking pin (22) and spring (23) are to be connected and fixed to be one, act on collet (20), collet (20) locates to have plural groove, chucking pin (22) just is stuck in the groove of collet (20), its clamping force is adjusted by adjusting nut (24), chucking pin (22) and spring (23) are stuck in the plural groove also by forming more than two.Same reason during use, is also carried out Job Operations by this special action bars.
