Description
Technical field
The utility model relates to the technical fields of cable fitting, more particularly, to a kind of high-voltage cable joint armored cassette.
Background technique
High-voltage cable joint is for the connection between high-tension cable ontology, but always HV CABLE SYSTEM is running thin
Weak link, in many accidents of Voltage Cable Lines Construction, the safety accident caused by high-voltage cable joint poor contact is the most
It is common.The raising of high-voltage cable joint temperature increases the contact resistance of joint, and high-voltage cable joint is caused to overheat, and aggravation is exhausted
Edge aging even causes insulation breakdown, causes to seriously threaten to the safe operation of electric system.Therefore, by cable connector
Between the position aluminium hydraulic pressed connecting pipe of connection (two sections of cable core conductors at) carry out infrared measurement of temperature, can effectively Monitoring High Voltage Cable connector run
Temperature change in the process has weight to the on-line monitoring for realizing high-voltage cable joint, the safe operation for improving Voltage Cable Lines Construction
Want meaning.
On the other hand, insulation breakdown occurs for intermediate joint of electric cable in order to prevent, and it is quick-fried to cause intermediate joint of electric cable
Fried accident, and related second accident, it is necessary to use intermediate joint of electric cable explosion-protection equipment.
After installing cable connector explosion-protection equipment additional, in order to discharge high pressure gas in time and completely cut off arc light, using reserved buffering
Space, while a certain number of gas discharge holes can be reserved in its shell, implement decompression release.At present in practice, electricity
The design that power cable intermediate joint explosion-protection equipment lets out energy hole is broadly divided into two kinds, and one is intermediate joint of electric cable explosion-protection equipments
Shell lets out energy hole toward two openings reserved on the convex surface of two sides are biggish between two parties, and another kind is on crust of the device surface while to reserve
Multiple openings are lesser to let out energy hole, both explosion-protection equipments design the barrier due to explosion-proof casing, cannot achieve cable connector
The infrared measurement of temperature at intermediate position.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of convenient for infrared measurement of temperature
High-voltage cable joint explosion-protection equipment, specific technical solution are as follows:

Armored cassette body upper part center, which is equipped with, lets out energy hole, and described let out can be equipped with connecting flange at hole, and connecting flange is equipped with
Gasket, the gasket are equipped with upper cover plate, and the upper cover plate is and the matched ring structure of connecting flange, the upper cover plate
It is connect with connecting flange by fastener.
The utility model passes through the center that will let out the top that explosion-proof box body is arranged in energy hole, avoids box body to electricity
The barrier of cable joint can carry out thermometric to cable connector by letting out energy hole, and can be equipped with gasket on hole letting out, and be not required to
It can play the role of waterproof when thermometric, gasket is equipped with upper cover plate, and connect by fastener with connecting flange, convenient for surveying
Dismounting when temperature operation.
Preferably, the energy hole of letting out is circular configuration, diameter is between 11cm ~ 14cm, further, described to let out
Energy bore dia is 12.5cm.
The change for letting out energy hole site will lead to the change of armored cassette internal pressure distribution.Thus, it is let out changing armored cassette
Behind energy hole site, needs to have redesigned the opening diameter for letting out energy hole, it is made to meet the function needs of armored cassette.Opening size is not
Can it is too small can not be too big, it is too small, can not sufficiently meet let out can effect the needs of, other equipment around will then be made greatly very much
At secondary destruction.
For the utility model by simulation calculation, available high-voltage cable joint armored cassette inside maximum gas pressure is straight with opening
The situation of change of diameter obtains aperture radius then by carrying out least square method fitting using matlab software to emulation data
With the functional relation between maximum gas pressure value inside armored cassette, derivation then is carried out to the function and is obtained in aperture radius and box body
The slope of function between maximum gas pressure value, slope represents in box body that maximum gas pressure value is with aperture radius change situation, when oblique
Show that atmospheric pressure value has tended to stationary value when rate is smaller, i.e. air pressure inside variation degree is not significant.By the above method, determine
When letting out energy bore dia between 11cm ~ 14cm, slope tends towards stability, and air pressure inside variation degree is not significant, will be worth among it
12.5cm is determined as maximum gas pressure value in box body with the variation tendency critical value from large to small of aperture radius.
Preferably, the gasket is rubber tabular structure, rubber seal efficiency is good, good corrosion resistance.
Preferably, the explosion-proof box body is the semi-cylindrical shaped structure of almag material.Aluminum-magnesium alloy material has
The features such as mechanically and chemically performance is stable, corrosion resistance is strong, while this material has better effects at datonation-inhibition aspect, can will be quick-fried
Fried power is greatly lowered, and achievees the purpose that Essential Safety, and inherently metal to a certain extent, heating conduction and strong
Spend especially prominent, be conducive to the exploitation of deep process technology, have specific strength is high, density is small, corrosion-resistant, recyclable, thermal conductivity is good,
Anti-electromagnetic radiation, can shaping thin wall plurality of advantages.
Preferably, the fastener is bolt, bolt arrangement is simple, easy to operate.
Compared with prior art, beneficial effect is:
The utility model due to devise aperture among high-voltage cable joint armored cassette let out can hole site, and using imitative
True calculate calculates opening diameter with Function Fitting, so that high-voltage cable joint armored cassette is both able to satisfy requirement of explosion proof, avoids
Secondary injury caused by connector explodes, and it is convenient for infrared measurement of temperature, and then grasp the operating status of cable connector, improve electricity
Cable joint operational reliability.
