Abstract
The utility model discloses a protection structure for a voltage secondary circuit connector lug. The protection structure comprises a fixed insulating shell and a secondary connector lug, wherein one end of the secondary connector lug extends into the fixed insulating shell and is connected with a voltage connection port in the fixed insulating shell, and the other end of the secondary connector lug extends out of the fixed insulating shell; the protection structure also comprises a movable insulating shell and a spring, wherein the spring is arranged in the fixed insulating shell in a sleeving manner, and one end of the movable insulating shell extends into the fixed insulating shell, forms a movable superposed structure with the fixed insulating shell, and abuts against the spring; and the end portion of the secondary connector lug extending out of the fixed insulating shell is covered by the movable insulating shell. According to the utility model, in the whole connection and subsequent use processes of electric equipment (such as a high voltage meter), the secondary connector lug is not directly exposed from the insulating shells (the fixed and movable insulating shells), thereby effectively avoiding short-circuit and grounding phenomena of the secondary connector lug, reducing the danger coefficient, and improving safety.
Description
Technical field
The utility model relates to the connector lug protection structure of voltage secondary circuit, and this protection structure is particularly suitable for the high-pressure gauge scale of transformer station and changes operation.
Background technology
It is that the high-pressure gauge scale will connected on the transformer substation voltage secondary loop connector lug is removed that the high-pressure gauge scale of transformer station is changed, the high-pressure gauge scale more renewed.At present, the connector lug primary structure of transformer substation voltage secondary loop is, comprise fixed insulation shell and secondary connection head, one end of secondary connection head stretches in the fixed insulation shell, and be connected with the voltage connectivity port on the fixed insulation shell, the voltage connectivity port of fixed insulation shell connects the power supply of transformer station, and the other end of secondary connection head extends the fixed insulation shell, extends the secondary connection head of fixed insulation shell with connecting the high pressure measurement table; Because the secondary connection head that extends the fixed insulation shell is not taked safeguard measure; always exposed outside the fixed insulation shell; in the replacing operation of high-pressure gauge scale and follow-up use, very easily be short-circuited, the phenomenon such as ground connection; danger greatly, has had a strong impact on operating personnel's life safety and device security.
Summary of the invention
The purpose of this utility model is: for above-mentioned the deficiencies in the prior art, provide a kind of voltage secondary circuit connector lug protection structure that can effectively avoid short circuit, grounding phenomenon to occur.
The technical solution adopted in the utility model is: a kind of voltage secondary circuit connector lug protection structure, comprise fixed insulation shell and secondary connection head, one end of described secondary connection head stretches in the fixed insulation shell, and with the voltage connectivity port on the fixed insulation shell, be connected, the other end of secondary connection head extends the fixed insulation shell; Also comprise movable insulation shell and spring, described spring housing is contained in the fixed insulation shell, and an end of described movable insulation shell stretches in the fixed insulation shell, survives fold with the fixed insulation hull shape and adds structure, stretches into movable insulation shell end and the spring butt of fixed insulation shell; The end that described secondary connection head extends the fixed insulation shell is covered by movable insulation shell.
The outer end diameter that described movable insulation shell stretches into the fixed insulation shell is greater than the inner end diameter of fixed insulation shell.
The end that described movable insulation shell stretches into the fixed insulation shell is bell-mouth structure of air.
The voltage connectivity port of described fixed insulation shell is provided with end cap.
The beneficial effects of the utility model are: above-mentioned protection structure has been set up movable insulation shell and spring on the basis of fixed insulation shell, the secondary connection head that extends the fixed insulation shell covers protection by movable insulation shell, for example, while connecting electric equipment (high-pressure gauge scale) on the secondary connection head when needs, movable insulation shell is pressed, the secondary connection head just can expose, when electric equipment connects when complete, under spring action, movable insulation is stretched out the fixed insulation shell and props up electric equipment, in the connection and follow-up use procedure of whole electric equipment, the secondary connection head can be directly not exposed outside insulation shell (fixed insulation shell and movable insulation shell), effectively avoided the secondary connection hair to give birth to short circuit, grounding phenomenon, reduced danger coefficient, improved fail safe.It has the characteristics such as reasonable in design, simple in structure, easy to operate, safe, reliable and practical.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model.
Code name implication in figure: 1-movable insulation shell; 2-fixed insulation shell; 3-secondary connection head; 4-voltage connectivity port; 5-spring.
Embodiment
Referring to Fig. 1: the utility model comprises movable insulation shell 1, fixed insulation shell 2, secondary connection head 3 and spring 5.Wherein, the tubular structure that movable insulation shell 1 is both ends open, an end end of movable insulation shell 1 is bell mouth shape.Fixed insulation shell 2 is the unlimited tubular structure of an end, the open end of fixed insulation shell 2 is cone-shaped, be provided with voltage connectivity port 4 on fixed insulation shell 2, voltage connectivity port 4 is arranged in the blind end place near fixed insulation shell 2, by voltage connectivity port 4, connects power supply.Spring 5 is sleeved in fixed insulation shell 2, and the flared end of movable insulation shell 1 cover is put in the tapering point of fixed insulation shell 2, and with fixed insulation shell 2 in spring 5 butts, under the effect of spring 5, movable insulation shell 1 stretches out in the interior realization of fixed insulation shell 2.In order to improve the assembling convenience of movable insulation shell 1 and fixed insulation shell 2, can consider fixed insulation shell 2 design mix segment structures, after movable insulation shell 1 is assembled into, is assembled into to integrative-structure by the fixed insulation shell 2 of segmentation again and gets final product.One end of secondary connection head 3 stretches in fixed insulation shell 2, and be connected with the voltage connectivity port 4 on fixed insulation shell 2, the other end of secondary connection head 3 extends fixed insulation shell 2, the end that secondary connection head 3 extends fixed insulation shell 2 is covered by movable insulation shell 1, and secondary connection head 3 use that covered by movable insulation shell 1 connect electric equipment (for example high-pressure gauge scale).Under the cooperation of movable insulation shell 1 and fixed insulation shell 2, secondary connection head 3 is covered fully, can't form exposed, effectively avoided that secondary connection head 3 is short-circuited, grounding phenomenon, reduced danger coefficient, improved fail safe, also can not connect electric equipment (for example high-pressure gauge scale) to secondary connection head 3 simultaneously and impact.
The voltage connectivity port 4 of above-mentioned fixed insulation shell 2 is provided with end cap.
