Description
Technical field
The present invention relates to power Transmission technical fields, and in particular to a kind of motor cooling electric wire.
Background technology
Electric wire is used for transmission and distributes the metallic conductor of electric energy, is frequently utilized for urban distribution network, the lead line in power station, work
The in-line power of mine enterprise and the submarine transmission line of crossing river and sea.In social development process, power circuit and transmission network
Middle electric wire plays an important role.
Tie of the electric wire as power transmission, also by the connecting line as motor and power supply.Either civilian motor is still
The output power of business electrical machine, motor is bigger, and the load for the electric wire being connect with motor is bigger.And traditional motor line,
It is by r c copper wire etc., after the motor overload working time is long, the temperature of electric wire can be significantly raised, closing electricity
Go mobile electric wire that can be clearly felt that Wire temperature is high after machine, and electro-insulating rubber layer is softened or is melted to insulate
Rubber layer is destroyed, and being destroyed the electric wire of electro-insulating rubber layer, there are certain danger, be easy to cause certain safety problem.I
Described burning line be exactly in fact because motor wire works overloadingly, to conductor generation high temperature by the insulating materials of package
It burns and causes the accidents such as fire, cause serious economic loss.
Invention content
The purpose of the present invention is to provide a kind of motor cooling electric wires, to be easy to cause when solving electric wire overwork
The problem of burning line.
In order to achieve the above objectives, the technical scheme is that：A kind of motor cooling electric wire includes successively from the inside to the outside
Conductor, asbestos layer and insulating layer, the asbestos layer are interior equipped with storage chamber and the through-hole being connected to storage chamber, the insulating layer top portion
It is equipped at intervals with several cooling bodies, the cooling body includes hollow block and the open tubular column that is set on the outside of hollow block, described, empty
Stem is fixedly connected with hollow block, and an inner cavity is constituted between hollow block and open tubular column, is fixed with vertical axes in hollow block, vertically
Axis is equipped with gap, slidably connects slide plate in vertical axes, hollow block is divided into epicoele and cavity of resorption, works as slide plate slides by the slide plate
It can be connected to epicoele when gap and cavity of resorption with through-hole by gap area, cavity of resorption, the inner cavity is equipped with and open tubular column vertical sliding
The driving plate of connection, driving plate are equipped with the outgassing nonreturn valve being connected to epicoele, and the gas outlet of outgassing nonreturn valve goes out towards epicoele
Gas check valve inlet is equipped with towards the inner cavity below driving plate, below driving plate to be fixed on open tubular column and is connected to outside
Breather check valve, driving plate are fixed by the connecting rod with slide plate and connect, the connecting rod and hollow block and the open tubular column company of sliding
It connects, the air flue for being connected to epicoele and being connected to outside is equipped in connecting rod.
The principle of the present invention：It is worked in motor so that when electric wire work, when the conductor load of electric wire is smaller, the heat that distributes
It is smaller, insufficient for the water in storage chamber by heating evaporation under the action of asbestos layer, when the load of conductor is excessive, cause to lead
Temperature is excessively high the pressure that lower intracavitary makes cavity of resorption can be entered by through-hole by the water heating evaporation in storage chamber, water vapour
Increase and push slide plate upward sliding, slide plate can drive driving plate upward sliding, driving plate upward sliding that can inner cavity be formed
To the suction of extraneous air, inner cavity sucks gas by breather check valve, and slide plate drive driving plate slides into the gap of vertical axes
When position, the water vapour of lower intracavitary can enter upper intracavitary by gap, and the pressure of epicoele and cavity of resorption reaches balance.In gravity
Under effect, slide plate can drive driving plate slide downward, and driving plate slide downward can be by outgassing nonreturn valve by the cold sky in inner cavity
Gas is expressed to intracavitary, and to which the cold air of upper intracavitary can condense water vapour, water vapour, which condenses, to be formed droplet and fall to slide plate
On.
The high temperature of conductor continues, by the water evaporation in storage chamber, the water vapour of intracavitary to be descended again to increase at this time, and cavity of resorption increases
Pressure can push slide plate upward sliding again and make slide plate slides to vertical axes gap position, the droplet on slide plate can pass through
Gap falls to cavity of resorption and enters in storage chamber and reuses along vertical axes.Air flue can let out the cold air of upper intracavitary
Pressure, avoids epicoele cold air is more so that water vapour cannot be introduced into intracavitary.
Beneficial effects of the present invention：(1) present invention can completely cut off conductor certain heat by asbestos layer, avoid conductor
It overheats in the loaded state and burns out insulating layer, conductor exposure is avoided to be contacted in air with other combustibles and generate fire
Calamity, the generation of preventing damage.
It (2), can be by water heating evaporation, to water when conductor load reaches certain value and temperature is increased to certain temperature
A large amount of heat can be taken away by forming water vapour, reduce the temperature of conductor.Water vapour condenses shape after meeting with cold air in epicoele
It at droplet and flows back into storage chamber, the droplet flowed back into storage chamber cools down to the water in storage chamber, and so on, to reach
To the purpose that conductor cools down, electric wire is avoided to burn line.
On the above base case：
Further preferably：The slide plate is equipped with the groove centered on vertical axes.Setting groove is for convenience by water
