Abstract
The invention relates to a cable house service device enabling cables to safely and conveniently enter and exit a cable cannel of a transformer substation (plant) and fully isolating moisture, smoke, fire, water, combustible gas and small animals in the cable cannel from entering the cable house service device in the transformer substation (plant). The cable house service device is made of a steel plate with the length of 1400mm, the width of 1200mm and the thickness of 5mm, and the steel plate is provided with 20 round cable house service holes with the diameter of 90mm for the cables to enter or exit a house; the front side of each house service hole is provided with a round steel protective tube for fixing and protecting a cable, and each steel protective tube is internally provided with a rubber protective sleeve and provided with a steel circular union cap at the upper port. The cable house service device is mounted by being fixed at the entry of the cable cannel by bolts, and the cables are respectively penetrated through the house service holes and the protective tubes; the center of each rubber protective sleeve is provided with a round hole with the same diameter as each cable, sleeved on each cable and pushed into each protective tube, and finally, the circular union cap is sleeved on each cable which is pushed at the upper port of each protective tube and screwed on the protective tube so as to press and compact the rubber protective sleeve in each protective tube.
Description
Affiliated technical field
The present invention relates to a kind of cable house service device that is used between power system transformer substation (institute) switchgear house cable turnover family and the cable trough, belong to power domain.
Background technology
At present, the transformer station of electric power system (institute), switchgear house, particularly the cable turnover family of the transformer station of industrial enterprise (institute), the overwhelming majority is passed in and out by cable trough, and mostly the shutoff of cable trough is to adopt fire barrier, fire prevention bag, anti-chamotte, fills sand and banket, even brick cement is stifled, though these methods are easy, can not realize thorough shutoff to cable trough.Because the lack of standard and the unreliability of above-mentioned method for blocking, very easily cause moisture, cigarette, fire, water, fuel gas and toy to enter in the transformer station (institute) by cable trough, thereby the safe operation to electric equipment constitutes a threat to, even cause the electric equipment accident, simultaneously, block up, prevent fires and wrap, prevent that chamotte, PLASTIC LAMINATED shutoff cable trough have also brought many inconvenience to daily replacing, maintenance and the maintenance at cable turnover family with brick cement.
Summary of the invention
For overcoming the deficiency that present cable house service shutoff exists, the invention provides a kind of cable house service device, this house service device not only can guarantee cable security, convenience, successfully pass in and out transformer station (institute), and can stop moisture, cigarette, fire, water, fuel gas and toy effectively and enter transformer station (institute) by cable trough, also provide convenience simultaneously for current check, maintenance and the replacing of cable.
The technical solution adopted for the present invention to solve the technical problems is: cable house service device is made by the steel plate of long 1400mm, wide 1200mm, thick 5mm; have the round cable house service hole of 20 diameter 90mm at current supply cable turnover family on the steel plate; the round steel protection tube that is used for fixing and protects cable is equipped with in front, house lead in hole; this protection tube has internal thread; be furnished with elastometric boot in the protection tube, removable, the threaded annular pressure cap of steel is arranged on the protection tube upper port.
When not wearing cable in the house lead in hole, elastometric boot is housed in the protection tube, threaded steel annular pressure cap tightly is spun on the protection tube upper port, and elastometric boot is squeezed in the protection tube firmly, and at this moment, the house lead in hole is a good seal.
During installation, cable house service device is fixed by bolts to transformer station cable trough house lead in mouth place, protection tube is in transformer station (institute).When need when a certain house lead in hole penetrates (or passing) cable, need screw off annular pressure cap at this protection tube port, take out the elastometric boot in the protection tube.Cable is penetrated in the transformer station through house lead in hole, protection tube by cable trough; simultaneously; a circular hole identical with cable size is opened at center at the elastometric boot that takes out; again elastometric boot is enclosed within on the cable; and elastometric boot is pushed in the protection tube, at last annular pressure cap also is enclosed within on the cable, and is pushed into the protection tube port; be screwed in the protection tube upper port, the elastometric boot in the protection tube is compressed get final product.If cable is thinner, can in same house lead in hole, wear several cables, simultaneously, put out several holes at preventing rubber and get final product.
The invention has the beneficial effects as follows: realized scientific, normalized cable trough shutoff mode; Moisture, cigarette, fire, water, fuel gas and toy have been stopped by the invasion and attack of cable trough in transformer station (institute); Make cable house service construction, more new cable is more time saving and energy saving, regular maintenance, service work are more simple and convenient; Thoroughly eliminated because the various hidden danger that cable trough shutoff difficulty brings for transformer station (institute) electric equipment safe operation.
