Background technique
Power cable（Hereinafter referred to as cable）It reliably and the advantages that being conducive to urban beautification is obtained with its power supply safety
It is more and more widely used, with the high speed development of national economy, power grid cables popularity is higher and higher, more and more
Cable focuses on cable duct, cable shaft or the subsurface that is laid in side by side, due to unit cable limited length, on a usual route
Need one or more connectors to carry out extension length, with and meet power reguirements.City prosperity location, industry intensive location, resident
Inhabitation location is all becoming cable compact district.It is not perfect due to cable fire-proof measure, there are different degrees of security risk,
In recent years because fire incident caused by cable constantly occurs, very big challenge is brought to resident living and factory safety.
According to power fault analysis, the reason of causing cable fire to occur is that cable intermediate joint production quality is inferior not
Together, connector is not tight, contact resistance is excessive, in During Process of Long-term Operation, will cause end overheat, breakdown insulation, leads to cable
Fire occurs for ditch or direct-buried cable.On the other hand, along with urban waterlogging, various acid, alkali, salt, etc. corrosive liquids pour into electricity
Cable ditch well generates corrosion to cable intermediate joint, and cable intermediate joint is mixed into the reasons such as aqueous vapor under wet weather, causes cable
It is easy to appear failures even to explode for transition joint.Also, the module for realizing real-time monitoring in the prior art is existed by setting
The outside electricity control module of armored cassette is connect with the sensor being arranged in armored cassette, the company of electricity control module and sensor
Connecing conducting wire is that the line outlet across armored cassette both ends is connect with sensor, and the electricity control module on the outside of armored cassette is easy by outer
The destruction of portion's liquid, steam external environment causes electricity control module to fail.Also, when cable intermediate joint failure is even quick-fried
When fried, connecting wire and sensor are destroyed, signal transmitting is influenced, also causes unnecessary economic loss.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of armored cassette of power cable connector monitoring running state.
Specifically, a kind of armored cassette of power cable connector monitoring running state, including upper housing and lower case, upper housing

At accommodating chamber, and accommodating chamber is connected to junction chamber.
It is provided with the through-hole for being connected in electronic control storehouse with accommodating chamber on the shell A, and through-hole is connected to junction chamber, leads to
It is provided with plug in hole, is provided with cable-through hole on plug.
The plug has flange, is equipped with screw on plug, plug is fixedly clamped by flange and plug cover
On shell A.
There is opening at the top of the shell A, the electronics warehouse lid for closing the opening is provided on shell A.
Screw thread is provided on the inside of the upper housing and lower case both ends.
The junction chamber both ends that the upper housing and lower case are formed are sealed by stifled mud of preventing fires.
The upper housing and lower case is bolted.
A kind of accident prevention method of the armored cassette of power cable connector monitoring running state, the interior setting of the armored cassette
There is the sensor for cable intermediate joint operating status in acquiring, when sensing data exception, cable intermediate joint has peace
When full hidden danger, maintenance personnel receives that there are the corresponding position of the cable intermediate joint of security risk and line informations, according to position
With line information to there are the routes of security risk to carry out isolation power failure, and to there are the progress of the cable intermediate joint of security risk
Maintenance.
The beneficial effects of the present invention are：Storehouse is controlled by design independent electronic, it is ensured that while explosion-proof performance, is also protected
Electricity control module has been demonstrate,proved not destroyed by outside liquid, steam external environment.The accommodating chamber for placing sensor is designed simultaneously, is avoided
Cable intermediate joint failure even explosion time, the damage of sensor and connecting wire.
