Abstract
The utility model discloses an anti-water-seepage plastic umbrella skirt for a junction box, which comprises a main umbrella-skirt body, wherein an umbrella-skirt fixed-locking device is arranged on the main umbrella-skirt body, and an umbrella-skirt threaded-locking device-fastening screw is arranged on the umbrella-skirt fixed-locking device. A locking slot is also arranged on the umbrella-skirt fixed-locking device. The main umbrella-skirt body is horn-shaped. When the anti-water-seepage plastic umbrella skirt is used, the plastic umbrella skirt is sleeved on an isolating-switch secondary-switching connecting-point junction box and an isolating-switch vertical pull rod near the lower ends, and after sealing glue is filled into the gap of the plastic umbrella skirt and the isolating-switch vertical pull rod, the upper part of the plastic umbrella skirt is heated by using an electrothermal plastic-packaging gun so that the plastic umbrella skirt is shrunk to be closely combined with the isolating-switch vertical pull rod without gaps, and finally, the plastic umbrella skirt is fixed by using the fixed-locking device. The anti-water-seepage plastic umbrella skirt has the characteristics of simple structure, simpleness and convenience in manufacture, no damage to equipment, safety and reliability, and the purpose of preventing rainwater from flowing into the secondary-switching connecting-point junction box along the isolating-switch vertical pull rod is achieved.
Description
Technical field
The utility model relates to a kind of electric power equipment, relates in particular to a kind of junction box's water-impervious plastic cement full skirt.
Background technology
In the season that weather rains; The poorly sealed isolating switch secondary changeover contact position of seeping water of bus isolating switch secondary changeover contact junction box and isolating switch vertical connecting rod rotatable connecting portion causes whole DC earthing number of times to account for total ground connection number of times more than 90%; It is the main cause that causes DC earthing; Therefore necessary head it off is eliminated this type of dc system grounding hidden danger.
The utility model content
In view of this, the purpose of the utility model provides bus isolating switch secondary changeover contact junction box, can prevent that rainwater from the isolating switch vertical connecting rod flows to secondary changeover contact junction box, having prevented DC earthing.
The technical scheme of the utility model realizes with following method,
A kind of junction box's water-impervious plastic cement full skirt comprises the full skirt main body, and wherein, the full skirt main body is provided with full skirt fixing and locking device, and full skirt fixing and locking device is provided with full skirt screw-threaded coupling device holding screw.
Also be provided with locking slot on the full skirt fixing and locking device.
The full skirt main body is tubaeform.
The good effect of the utility model technical scheme is:
The utlity model has simple in structure, make simple and convenient, do not damage equipment, safe and reliable characteristics, reached and prevented the purpose of rainwater in the isolating switch vertical connecting rod flows to secondary changeover contact junction box, prevented DC earthing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural scheme of mechanism of full skirt fixing and locking device among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Can be found out that by Fig. 1 and Fig. 2 this junction box water-impervious plastic cement full skirt comprises full skirt main body 1, wherein, full skirt main body 1 is provided with full skirt fixing and locking device 2, and full skirt fixing and locking device 2 is provided with full skirt screw-threaded coupling device holding screw 3.
It can also be seen that by Fig. 2, also be provided with locking slot 4 on the full skirt fixing and locking device 2.
It can also be seen that by Fig. 1 full skirt main body 1 is tubaeform.
During use; Isolating switch secondary changeover contact junction box and isolating switch vertical connecting rod are put full skirt near the lower end; Behind filling fluid sealant in full skirt main body and the isolating switch vertical connecting rod gap; Electricity consumption thermoplastic envelope rifle with the heating of full skirt main body top make its shrink combine with the isolating switch vertical connecting rod closely seamless, at last with the fixing full skirt main body of fixing and locking device.
