Abstract
The utility model discloses a cable control by temperature change alarm, include cable socket and the cable core that passes cable socket, the cable socket inboard is provided with temperature sensor, the temperature sensor electricity is connected with the temperature controller, the temperature controller electricity is connected with the alarm, the temperature controller electricity is connected with the circuit breaker, the circuit breaker concatenates in the cable. The utility model discloses a cable control by temperature change alarm is inserting temperature sensor in cable socket's the cable core, the temperature is transmitted for the temperature controller, and during upper limit value on the temperature reaches the temperature controller, the shunt opening coil on this way circuit breaker can be given by output current to the temperature controller, makes the outage of shunt release action circuit breaker to send out the police dispatch newspaper, in time the adjustment load plays the protection of cables effect.
Description
Technical field
This utility model relates to a kind of attemperating unit, is specifically related to a kind of cable temperature-control alarm, belongs to cable temperature control system technical field.
Background technology
Cable, usually by the cable of the similar rope of several or several groups wire strandings, is often organized mutually insulated between wire, and is often twisted into round a center, and whole outside is surrounded by the cover layer of high-insulation；Cable has interior energising, the feature of external insulation；General 110kV oil-impregnated paper insulation cable maximum permissible temperature less than 60 DEG C, be laid in underground time less than 45 DEG C；Temperature exceedes the consequence of permissible value generation: (1) accelerates insulation ag(e)ing；(2) oil expands and produces oil pressure, makes sheath or the deformation of aluminum bag, is internally formed space, damages cable；When the electric current of cable is big, generating heat rapidly, it is likely to cause tripping operation, if not having the equipment of Current limited Control on circuit, then cable is crossed thermally-induced fire and is likely to；Accordingly, it would be desirable to develop the equipment being specifically designed for cable temperature control alarming.
Utility model content
For solving the problems referred to above, the utility model proposes a kind of cable temperature-control alarm, when temperature reaches the higher limit on temperature controller, temperature controller can control chopper power-off, and sends alarm, timely Load adjustment, plays protection cable effect.
Cable temperature-control alarm of the present utility model, including the cable core of cable socket and traverse cable socket, the temperature sensor being provided with inside described cable socket, described temperature sensor is electrically connected with temperature controller, described temperature controller is electrically connected with alarm, and described temperature controller is electrically connected with chopper；Described chopper is serially connected with in cable.
Further, described temperature controller and cable connector are installed on a box inside, and described alarm is installed on outside casing.
Yet further, described casing is provided with visual window in temperature controller place.
Further, described temperature controller electrically connects with the shunt opening coil of chopper.
As preferred embodiment, described cable core is coated on temperature sensor periphery.
This utility model is compared with prior art; cable temperature-control alarm of the present utility model; temperature sensor is inserted in the cable core of cable socket; temperature is transferred to temperature controller, and when temperature reaches the higher limit of temperature controller, temperature controller can export electric current to the shunt opening coil on this circuit breaker; make shunt release action breaker power-off; and send alarm, timely Load adjustment, play protection cable effect.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1-cable socket, 2-cable core, 3-temperature sensor, 4-temperature controller, 5-alarm, 6-chopper, 7-casing.
Detailed description of the invention
Cable temperature-control alarm as shown in Figure 1, including the cable core 2 of cable socket 1 and traverse cable socket, being provided with temperature sensor 3 inside described cable socket, described temperature sensor is electrically connected with temperature controller 4, described temperature controller is electrically connected with alarm 5, and described temperature controller is electrically connected with chopper 6；Described chopper 6 is serially connected with in cable.
Described temperature controller 4 and cable connector 1 are installed on inside a casing 7, and described alarm 5 is installed on outside casing 7.
Described casing 7 is provided with visual window (not shown) in temperature controller 4 place.
Described temperature controller 4 electrically connects with the shunt opening coil of chopper 6.
It is peripheral that described cable core 2 is coated on temperature sensor 3.
Cable temperature-control alarm of the present utility model; temperature sensor is inserted in the cable core of cable socket; temperature is transferred to temperature controller; when temperature reaches the higher limit of temperature controller; temperature controller can export electric current to the shunt opening coil on this circuit breaker, makes shunt release action breaker power-off, and sends alarm; timely Load adjustment, plays protection cable effect.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, it is necessary to determine its technical scope according to right.
