Background technique
With the development of urban construction, cable transmission line is using more and more extensive.There are in many between cable connection
Between connector, connector is also easy to produce aging during long-play, short circuit phenomenon occurs, or even explosion occurs so that causing fire
Calamity causes heavy losses.Transition joint is typically mounted at cable duct, in cable tunnel, often has ponding, connector long period of soaking exists
In water, there are larger hidden dangers for butt joint operation；There is very big security risk in the connector that protection is therefore not added.Therefore, it is necessary to
The installation of transition joint part has waterproof, explosion-proof, fire-proof function protective shell.
Waterproof anti-explosion connector box various types currently on the market, most of is that upper and lower half-shell is bolted form, cut cable
Portion and ground connection wire outlet part cannot effective waterproofs；Cable intermediate joint itself has higher running temperature, after installing anti-riot shell additional, fortune
Trip temperature will be higher, greatly improve failure rate, influence connector safe operation；Waterproof anti-explosion connector box substantially cannot currently on the market
Fire preventing occurs, and timely and effective cannot put out a fire after on fire；, cannot be effectively explosion-proof after joint fault breakdown and explosion, it cannot prevent
Disaster expands.
Summary of the invention
To solve the above-mentioned problems, the invention proposes a kind of high-voltage cable middle joint waterproof anti-explosion flame failure protection shell,
Including high-tension cable and joint housing, which is characterized in that further include left shell and right shell body, the joint housing is arranged in left housing
The inside of body and right shell body, the left shell are fixedly connected with right shell body by rubber pad, the left side of the left shell and right shell
High-tension cable outlet portion is all connected on the right of body, one end that the left shell connects high-tension cable outlet portion with right shell body is equipped with
Pressure relief opening, successively installs sealing shroud and wedging ring on the outlet portion outer wall of the high-tension cable, in the left shell and right shell body
Fibre pipe is installed on wall, heat-dissipating pipe is equipped in the left shell and right shell body, fire trace tube is installed in the joint housing, it is described
Fire trace tube connects fire suppression bottle.
Further, the cross sectional shape of the left shell and right shell body is rectangular, round or polygon.
Further, the rubber pad is made of corrosion resistant high elastic rubber.
Further, the sealing shroud uses high resiliency corrosion resistant rubber material.
Further, the fibre pipe uses glass fibre, aramid fiber, Kafra fiber or carbon fibre materials.
A kind of high-voltage cable middle joint waterproof anti-explosion flame failure protection shell proposed by the present invention, has the advantage that this hair
It is bright to use corrosion resistant high elastic rubber, it can be with permanently effective reliable waterproof；Ventilation and heat pipe is added inside protective shell, it can be effective
Connector running temperature is reduced, failure risk is greatly reduced, increases the explosion-proof intensity of shell；Left half section and it is right half section equipped with it is whole around
High-strength explosion-proof fibre pipe processed reaches effectively explosion-proof；It is externally wrapped with fire trace tube in joint housing, and connects fire suppression bottle, it can be quick
Fire extinguishing cooling, fire preventing occur, and improve reliability.

Specific embodiment
With reference to the accompanying drawing to a kind of specific implementation of high-voltage cable middle joint waterproof anti-explosion flame failure protection shell of the present invention
Mode is described in detail, and examples are only for illustrating the present invention and not for limiting the scope of the present invention for this, art technology
Personnel fall within the application range as defined in the appended claims to the modification of various equivalent forms of the invention.
Such as Fig. 1, a kind of high-voltage cable middle joint waterproof anti-explosion flame failure protection shell, in cable passage under protecting field
The safety of high-voltage cable joint, including left shell 2 and right shell body 7, the left shell 2 and right shell body 7 pass through rubber pad 12 and spiral shell
Bolt is fixedly connected, and rubber pad 12 uses corrosion resistant high elastic rubber, and it is medium to cope with long period of soaking water by whole pressure resistance 1.0MPa or more
Adverse circumstances, the another side that left shell 2 is connect with right shell body 7 are connected with 3 wire outlet part of high-tension cable, left shell 2 and right shell body 7
Cross sectional shape be rectangular, round or polygon, such as Fig. 4, the cross sectional shape of right shell body 7 is circle；Such as Fig. 3, high-tension cable 3 goes out
Line position outer layer is successively held tightly by sealing shroud 10 and wedging ring 9, and sealing shroud 10 uses high resiliency corrosion resistant rubber material, reaches effective
Waterproof；Such as Fig. 2, enclosure interior is equipped with more heat-dissipating pipes 4, and heat-dissipating pipe 4 not only increases 100% heat dissipation area, and left
It is right to form cross-ventilation, the running temperature of cable connector is effectively reduced, greatly reduces failure risk, heat-dissipating pipe 4 can also rise
To shell booster action, shell explosion-proof capabilities are improved；Equipped with the high-strength anti-of whole coiling on 7 inner wall of left shell 2 and right shell body
Quick-fried fibre pipe 6, fibre pipe 6 are using glass fibre, aramid fiber, Kafra fiber or carbon fibre materials, Kafra fiber, carbon fiber
Material for antiballistic protective clothing can achieve the purpose that really effectively explosion-proof, such as Fig. 5, be wound with fire trace tube 11 outside joint housing 5, fire is visited
Extend right shell body 7 after the connection heat-dissipating pipe 4 of pipe 11 to connect with fire suppression bottle 8.
The course of work of the invention is, after cable connector is installed, around upper fire trace tube 11 outside joint housing 5,
And it is connected to fire suppression bottle 8, left shell 2 is fixedly connected by intermediate rubber pad 12 with bolt with right shell body 7, in high-tension cable 3
Outside holds sealing shroud 10 and wedging ring 9 tightly, when cable connector running temperature is excessively high, is carried out by the ventilation of heat-dissipating pipe 4 or so scattered
Heat；When explosion time occurs for joint fault, whole coiling high-strength explosion-proof fibre pipe 6 can be effectively explosion-proof, disaster is not expanded to other
Facility；When 5 temperature of joint housing reaches 150 DEG C, protective shell is externally wrapped with the softening rupture of fire trace tube 11, and triggering fire suppression bottle 8 sprays
Extinguishing chemical fire extinguishing cooling is penetrated, fire is prevented.
Connector running temperature can be effectively reduced in the present invention, greatly reduce failure risk, increase the explosion-proof intensity of shell.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited to above-mentioned realities
The detail in mode is applied, within the scope of the technical concept of the present invention, a variety of letters can be carried out to technical solution of the present invention
Monotropic type, these simple variants all belong to the scope of protection of the present invention.
