Background technology
At present, the power equipment terminal studs such as transformer, lightning arrester and outdoor switch are generally outside exposed, due to people for touching, stealing, toy or foreign material take the reasons such as tactile, condensation flashover, pollution flashover, salt fog, acid rain and chemical corrosion, power equipment damages, have a power failure and the Frequent Accidents such as electric shock loss of life or personal injury.
For preventing the terminal stud of transformer outside exposed, market there are some safety devices, the electro-insulating rubber cover that general employing adapts to termination external shape is to isolate termination and extraneous contact, and reserved lead channels, for the connection of external connection and external device (ED).But, because the size and shape of the terminal stud of transformer differs, and the angle of external connection and terminal stud differs, and causing needs to be equipped with different safety devices to adapt to the trend of external connection to dissimilar terminal stud, thus cause cost to increase, also for installation makes troubles.
Summary of the invention
In view of this, the utility model provides a kind of New insulated sheath, needs to be equipped with different safety devices to adapt to the trend of external connection to dissimilar terminal stud to solve, thus causes cost increase and install troublesome technical problem.
The technical scheme adopted:
A kind of New insulated sheath is provided, comprise terminal cover and extend pipe box, described terminal cover is overlapped by conical bottom and cylindricality spacer shell forms, described conical bottom cover and cylindricality spacer shell one-body molded, described cylindricality spacer shell outer wall arranges collar flange, and some vees are offered at the top of described cylindricality spacer shell; One end that described extension pipe box is connected with terminal cover arranges telescoping tube, and the other end arranges line outlet, and described telescoping tube is arranged on described cylindricality spacer shell by tube connector, and described tube connector inwall offers the groove suitable with described collar flange.
Further, in order to easy for installation, the longitudinal direction of described insulating sleeve arranges opening, and described opening is fastened by rubber tack.
Preferably, the outer wall of described cylindricality spacer shell also arranges sheath, the inner chamber of described sheath and the intracavity inter-connection of cylindricality spacer shell, and the material of described sheath is temperature-sensitive silicon rubber.
Preferably, the diameter of described extension pipe box inner chamber is less than the diameter of described cylindricality spacer shell inner chamber, increases the stability that described terminal cover is connected with described extension pipe box.
Preferably, described terminal cover and to extend the material of pipe box be that silastic elastomer is high temperature vulcanized forms.
Preferably, the inwall of described terminal cover and extension pipe box is provided with insulating barrier.
Beneficial effect: insulating sleeve of the present utility model comprises the terminal cover and extension pipe box that fit together, can adapt to difform binding post; The angle being arranged so that arbitrarily can to adjust terminal cover and extend pipe box of telescoping tube, to adapt to the difference trend of external connection, thus without the need to being equipped with multiple insulating sleeve, reducing costs, installing simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of New insulated sheath of the present utility model;
Fig. 2 is the structural representation of terminal cover of the present utility model;
Fig. 3 is the structural representation of extension pipe box of the present utility model.
Embodiment
The following description and drawings illustrate specific embodiment of the invention scheme fully, to enable those skilled in the art to put into practice them.Other embodiments can comprise structure, logic, electric, process and other change.Embodiment only represents possible change.Unless explicitly requested, otherwise independent parts and function are optional, and the order of operation can change.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.
In some illustrative embodiments, as shown in Figures 1 to 3, a kind of New insulated sheath is provided; comprise terminal cover and extend pipe box 5; terminal cover, for the protection of the termination of transformer, extends the passage of pipe box 5 as external connection, and the lead-in wire being connected on termination is drawn from extending in pipe box 5.
Terminal cover is made up of conical bottom cover 1 and cylindricality spacer shell 2, and wherein, it is one-body molded that conical bottom cover 1 and cylindricality spacer shell 2 add man-hour.Cylindricality spacer shell 2 outer wall arranges collar flange 3, and cylindricality spacer shell 2 offers some vees 4 in the part being positioned at collar flange more than 3, and vee 4 is uniformly distributed, and makes the top indentation of cylindricality spacer shell 2.
Extend pipe box 5 one end and arrange telescoping tube 6, the other end arranges line outlet 7, extends pipe box 5 and is connected with terminal cover by telescoping tube 6.Telescoping tube 6 adopts the bellows of adjustable direction and length, and one end that telescoping tube 6 is connected with cylindricality spacer shell 2 arranges tube connector 8, and telescoping tube 6 is arranged on cylindricality spacer shell 2 by tube connector 8.
The inwall of tube connector 8 offers the groove 9 suitable with collar flange 3.During installation, first terminal cover is arranged on the termination of transformer, again extension pipe box 5 is enclosed within the external connection of transformer, the length of adjustment telescoping tube 6 and direction, suitably bending telescoping tube 6, is sleeved on the outer surface of cylindricality spacer shell 2, makes collar flange 3 embed in groove 9 by tube connector 8, thus, terminal cover and extension pipe box 5 are installed together.Regardless of the direction of external connection, only need adjust telescoping tube, without the need to being equipped with different protective covers for different terminations, reduce costs, reducing installation difficulty simultaneously.
In some illustrative embodiments, the longitudinal direction of insulating sleeve arranges opening, and opening is fastened by rubber tack 10, is convenient to install, and from opening part, insulating sleeve is opened a certain size breach, insulating sleeve is wrapped transformer termination during installation.
In some illustrative embodiments, the outer wall of cylindricality spacer shell 2 also arranges sheath 11, the inner chamber of sheath 11 and the intracavity inter-connection of cylindricality spacer shell 2, and the material of described sheath 11 is temperature-sensitive silicon rubber.Sheath 11 not only can expand the intracavity space of cylindricality spacer shell 2, be convenient to heat radiation and install, and material is temperature-sensitive silicon rubber, can vary with temperature and variable color, plays forewarning function when temperature is too high.
In some illustrative embodiments, the diameter of described extension pipe box 5 inner chamber is less than the diameter of cylindricality spacer shell 2 inner chamber.When extension pipe box 5 is arranged on terminal cover, the part of cylindricality spacer shell 2 indentation stretches into and extends in pipe box 5, and the part between vee 4 gathers mutually the outside tension force of generation one, thus, can avoid extending on pipe box 5 word terminal cover and come off, increase bonding strength.
In some illustrative embodiments, described terminal cover and to extend the material of pipe box 5 be that silastic elastomer is high temperature vulcanized forms, has not modification, high-flexibility, the feature that life of product is long.
In some illustrative embodiments, the inwall of described terminal cover and extension pipe box 5 is provided with insulating barrier, plays insulation effect, prevents the person caused because electrical contact point is exposed from getting an electric shock.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; other are any do not deviate from Spirit Essence of the present utility model and principle under the change made; modify; substitute, combination, simplify; all should be the substitute mode of equivalence, all should be included in protection range of the present utility model.
