Abstract
The invention discloses a novel PT insulating sheath. The novel PT insulating sheath is divided into a T-shaped PT insulating sheath and an L-shaped PT insulating sheath, wherein the L-shaped PT insulating sheath comprises a transverse sheath and a longitudinal sheath which are connected with each other; the T-shaped PT insulating sheath comprises a top cap, a central sheath and a column sheath, the top cap is connected with the upper end of the central sheath, and the column sheath is connected with the lower end of the central sheath; the transverse sheath is a hollow cylinder; the longitudinal sheath is a hollow cylinder in which the top end is closed; the central sheath is a hollow cube with two round holes respectively formed in the upper part and the lower part; the column sheath is a hollow cylinder; The novel PT insulating sheath respectively meets different copper bar lapping manners, has excellent insulating performance and good elasticity, can resist corrosion and ageing and is easy to mount; the insulating performance is improved, and the mounting distance is reduced; the novel PT insulating sheath is convenient to overhaul and repeatedly use and is beneficial to the miniaturization development of devices.
Description
Technical field
The present invention relates to switch cubicle insulation protection field, relate in particular to a kind of novel PT insulating sleeve.
Background technology
At present, in transformer station, for preventing voltage transformer (PT) safeties fuse failure, cause measuring voltage to be forbidden, have a strong impact on the normal operation of voltage transformer, need to change in time the PT safeties.But, when changing, often can occur because the two ends of safeties are the conducting metal end cap, under the long-term environmental activity such as moist, as to drench with rain, cause the internal thread corrosion of safeties, hinder and change normally; Secondly, to conducting metal end cap and safeties, the position, space is arranged, the meeting such as dust, winged insect damage insurance device, cause the PT safeties easily because being infected with dust, reducing insulation property, even can not normally use.
Summary of the invention
The objective of the invention is for addressing the above problem, a kind of novel PT insulating sleeve is provided, this insulating sleeve reduces the space between safeties and conducting metal end cap effectively, and drenching with rain, in moist environment, the protection safeties are not corroded.
For realizing above technical purpose, the present invention by the following technical solutions.
A kind of novel PT insulating sleeve, be divided into T-shaped and L-type; Wherein L-type PT insulating sleeve, comprise interconnective horizontal cover and longitudinal sleeve; T-shaped PT insulating sleeve, comprise top cap, center and column sleeve, and the top cap connects the upper end of center, and column sleeve connects the lower end of center.
Described horizontal cover is hollow cylinder.
The hollow cylinder that described longitudinal sleeve is top closure.
Described center is for respectively there being up and down the hollow cubic body of a circular hole.
Described column sleeve is hollow cylinder.
The invention has the beneficial effects as follows: meet respectively different copper bar overlapping modes, insulation property are good, corrosion-resistant, anti-aging, and good springiness is easy to install, and improves insulation property, dwindles mounting distance, and the easy access recycling, be conducive to the development of device miniaturization.
The accompanying drawing explanation
The structure chart that Fig. 1 is the novel PT insulating sleeve of L-type of the present invention;
The structure chart that Fig. 2 is T-shaped novel PT insulating sleeve of the present invention.
Wherein, 1, horizontal cover; 2, longitudinal sleeve; 3, top cap; 4, center; 5, column sleeve.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, 2, a kind of novel PT insulating sleeve, be divided into T-shaped and L-type, meets respectively different copper bar overlapping modes; Wherein L-type PT insulating sleeve, comprise interconnective horizontal cover 1 and longitudinal sleeve 2; T-shaped PT insulating sleeve, comprise top cap 3, center 4 and column sleeve 5, and top cap 3 connects the upper end of center 4, and column sleeve 5 connects the lower end of center 4.
Laterally cover 1 is hollow cylinder.
The hollow cylinder that longitudinal sleeve 2 is top closure.
Before the PT insulating sleeve is installed, first copper bar is pierced in sheath, after installing, sheath is fixed on to the faying surface place by shape, the PT insulating sleeve adopts the silicon rubber material, one machine-shaping, and all sizes are formulated according to the size of different copper bars.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
