Abstract
The utility model provides a protection device that is used for cable intermediate head under salt fog humid environment of harbour, is including preventing hot wall, electric cable frame bridge, cable and explosion -proof box, prevent that the fixed arrangement of hot wall is on bridge at electric cable frame, the cable pass and prevent hot wall and explosion -proof box being provided with cable intermediate head on one of them cable, the peripheral winding of cable intermediate head has the temperature measurement optical cable, temperature measurement optical cable and cable intermediate head are located inside the explosion -proof box. The utility model discloses an ingenious explosion -proof box of setting and add and to establish the temperature measurement optical cable can the effectual fire prevention of accomplishing the cable, and the real time monitoring of cable joint temperature can also provide continuous temperature dynamic monitoring signal, and the operator on duty of being convenient for is discover hidden danger in advance and is in time handled, prevent hot wall's setting and strengthen the processing to cable intermediate head, reduced to cause the trend of further expansion greatly after the conflagration takes place, carry out effectual protection to the equipment beyond the cable.
Description
Technical field
This utility model relates to a kind of connector protection device, particularly relates to a kind of under the salt fog wet environment of harbour
6, the protection device of 10kV cable intermediate joint.
Background technology
From the point of view of, 10kV cable existing 6 according to harbour uses experience for many years, this cable is using more than 3 years
It is aging that rear cable there may be insulation sheath, and cable jacket is stiff, and no longer possesses toughness characteristics,
Oversheath is poorly sealed causes salt fog wet gas to enter inside end, thus causes cable fault frequent
Occur.Cable intermediate joint is commonly positioned in cable testing bridge, and cable intermediate joint once catches fire,
To periphery, other run cable run, facility and personnel and cause the biggest harm, even can cause second accident
Generation, expand further power outage scope and bring massive losses to each big business and factory.
Summary of the invention
To be solved in the utility model it has a problem in that offer is a kind of under the salt fog wet environment of harbour 6,10kV
The protection device of cable intermediate joint, when there is temperature anomaly in cable intermediate joint, it is possible to achieve early warning,
After fire occurs, spreading further of fire, the equipment beyond protection cable can be controlled.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of protection device of cable intermediate joint under the salt fog wet environment of harbour, including fire wall, cable
Bridge formation, cable and armored cassette, described fire wall is fixedly mounted on cable bridge formation, and described cable is through fire prevention
Wall and armored cassette, be wherein provided with cable intermediate joint on a cable, and cable intermediate joint periphery is wound with survey
Temperature optical cable, temperature measuring optical cable and cable intermediate joint are positioned at inside armored cassette.
Described fire wall number is two, and in round pie, two fire walls are respectively in cable intermediate joint both sides.
Described fire wall use material have tasteless, nontoxic, fire prevention, oil resistance, its oxygen index (OI) is
100, fire resistance period reaches more than 3 hours.
It is cast with fireproof coating inside described armored cassette.
The beneficial effects of the utility model: arranged armored cassette by ingenious and added temperature measuring optical cable, can be effective
Accomplish fireproofing of cable, the real-time monitoring of temperature of cable junction, and early warning, it is also possible to continuous print temperature is provided
Degree dynamic monitoring signal, it is simple to operator on duty scents a hidden danger in advance and processes in time；The setting of fire wall and strengthen right
The process of cable intermediate joint, substantially reduces after fire occurs and causes the trend expanded further, to electricity
Equipment beyond cable is effectively protected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Wherein, 1-cable is built bridge, 2-fire wall, 3-temperature measuring optical cable, 4-cable intermediate joint, 5-armored cassette, 6-
Cable.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this reality
It is set forth in novel embodiment.
A kind of protection device of cable intermediate joint under the salt fog wet environment of harbour, including fire wall 2, electricity
Cable bridge formation 1, cable 6 and armored cassette 5, described fire wall 2 is fixedly mounted on cable bridge formation 1, described
Cable 6, through fire wall 2 and armored cassette 5, is wherein provided with cable intermediate joint 4 on a cable 6, electricity
Cable transition joint 4 periphery is wound with temperature measuring optical cable 3, and temperature measuring optical cable 3 can realize monitoring cable 6 temperature in real time,
And remote alarms can be realized after abnormal temperature being detected；Temperature measuring optical cable 3 and cable 6 transition joint 4
It is positioned at armored cassette 5 internal.
Described fire wall 2 number is two, and in round pie, two fire walls 2 are respectively in cable intermediate joint 4
Both sides, to the damage of facilities beyond cable 6 after can effectively preventing fire from occurring.
Described fire wall 2 use material have tasteless, nontoxic, fire prevention, oil resistance, its oxygen index (OI) is
100, fire resistance period reaches more than three hours.
Described armored cassette 5 is internal is cast with fireproof coating.
Above an embodiment of the present utility model is described in detail, but described content has been only this practicality newly
The preferred embodiment of type, it is impossible to be considered for limiting practical range of the present utility model.All according to this utility model
Impartial change that application range is made and improvement etc., all should still belong to patent covering scope of the present utility model it
In.
