Abstract
The utility model discloses a kind of conductor temperature measuring type T-type cable connector devices, belong to power equipment monitoring field, which includes：It is close to the sensor and external temperature display device of T-type cable connector conductor terminals or connected tail plug metal body surface.It is installed on the sensor inside connector and does not use battery, need not safeguard.Sensor is integrally located inside conductor equipotential volume, will not be designed T-type cable connector electric field and be had a negative impact, sensor can be with long-term work during entire service life with T-type cable connector.The utility model can find T-type cable connector terminal and equipment bad connection, can set corresponding alarm temperature, avoid further causing failure in time by monitoring the temperature of the point.On the other hand the data during whole service can be collected, the load condition in entire circuit is monitored, foundation can be provided for the adjustment of load.
Description
Technical field
The utility model belongs to power equipment middle cable connector field of temperature measurement, and in particular to is carried out to cable conductor temperature real
When monitoring cable connector device.
Background technology
With the rapid development of economy, the demand of electric power is also being continuously increased.The production and living of modern society are all the time
It is all be unable to do without the demand to electricity, at the same time operation of power networks failure can all upset the production and life of normal society, institute each time
There is quite high importance with the safe operation of power grid.And equipment running temperature is investigate primary equipment safe operation one
Important parameter, therefore the direct temperature monitoring of power equipment just has very important value.
In the power system, electric current is mainly transmitted by conductor, is the source of fever, and the fever of other outsides is most
Derived from the conductor of current-carrying, but either low pressure or high-pressure conductor, it is dielectrically separated from outside.Voltage is higher, and insulating layer is got over
Thickness when voltage is more than 3kV, can design semi-conductive layer and carry out electric field homogenizing, with the raising of voltage, the model of power supply inside and outside insulation
Enclosing can expand, and the importance of circuit also improves gradually.Therefore how the running temperature of conductor directly measure to transport inspection department
Seem very crucial and important for door, but there is also many difficult points, for example signal how to be allowed to penetrate insulation and shielded layer, this is
It is at present for technological means or relatively difficult, simultaneously as sensor requirements are coated on inside insulating layer completely, for stabilization
Property and non-maintaining requirement are very high.
It is directed to case above, we are further studied on the basis of current existing thermometry, target
It is to carry out direct temperature measurement to being coated on the conductor inside insulating layer.In conjunction with the research and development and application of advanced wireless passive sensor, I
System is directly monitored using novel intelligent wireless temperature, realize directly monitoring power equipment connecting portion temperature effective in real time
Situation of change.Temperature-sensing element is tightly attached to the surface of testee, truly reflects the real time temperature of equipment surface, and requirement pair
Running equipment does not have any influence.In conjunction with backstage temperature monitoring system, when the running temperature of equipment is more than default alarm temperature value
When, system auto-alarming, operation department takes adequate measures in time, avoids causing equipment fault since temperature raises, protects
Demonstrate,prove power grid security reliability service.
Utility model content
The utility model is collectively constituted by built-in sensors and external reception device.Built-in sensor is by capacitance and electricity
Sense is composed in series, and appearance and size and tail plug coordinate, and the metal insert inner wall that is placed on inside T connector tail plug or is tightly attached to metal
Inserts dead astern is cast in epoxy plug.External reception device need not be in direct contact with sensor, need to be in concentric circular fashion
It places.Capacitance is in a linear relationship with temperature as temperature-sensing element.External reception device is by resonance come capacitance in detection sensor
With the variable quantity with inductor combination body, it is then converted into corresponding temperature value.Built-in sensors need not use power supply, outside to receive
Antenna needs lasting working power, the variation of continual detection internal sensor parameter, to realize reflect it is corresponding
Temperature relation.
The utility model is different from existing conductor on-line temperature monitoring device, and all temperature measurement components are not in connector electric field
In the range of intensity distribution, original product electric property is not interfered with.Temperature measuring point is consistent with target point, and can pass in real time
It is defeated, the temperature of energy effecting reaction conductor.Monitoring reliability and durability are improved,
Temperature signal inside external reception device one side reception, while the information is passed into backstage, need outside
Power supply.
Advantageous effect
As needed, sensor can be built in inside the tail plug of T-type cable connector, can also when product is installed,
It is placed on conductor, which can be applicable according to different manufacturers by adjusting appearance and size.For having installed
Product, the tail plug with sensor can be replaced, you can realize by original product up-gradation at temperature measuring type product.
The product of the utility model can monitor conductor point in real time after installation, reflect the situation of change of temperature in time, can
Following purposes is realized to help：
1) accidental power failure is reduced：By three it is alternate compared, in time find temperature anomalous variation, judge potential faults
2) economy of cable loop operation and increase-volume provide foundation：Real-time monitoring temperature collects 1 year electricity consumption feelings
Condition, it is possible to determine that the section of cable can increase-volume offer data supporting.
Description of the drawings
Fig. 1 is temperature measuring type T connector sensor and the reception device location drawing.
Fig. 2 is that temperature transducer is placed on metal insert inner wall.
Fig. 3 is that temperature transducer is placed on metal insert dead astern, is cast in epoxy part：
In figure：The external reception antennas of 1-；2- built-in sensors；3- studs；4- metal inserts；5- tail plugs；6- conductors
Terminal.
Specific implementation mode
Fig. 1 is temperature measuring type T connector sensor and the reception device location drawing.External reception device 1 is placed on T connector sheet
Outside body, placed in concentric circles with built-in sensors 2.The interior design phase of the placement location of built-in sensors 2 and T connector
It closes, built-in sensors 2 metal insert 4 can be placed on when the cavity that conductor terminals 6 and metal insert 4 surround has the gap
Inner wall, the modes of emplacement are shown in described in Fig. 2.When the cavity that conductor terminals 6 and metal insert 4 surround does not have gap, can only place
In 4 tail portion 5 of metal insert, which sees Fig. 3.
Fig. 2 is that built-in sensors 2 are placed on 4 inner wall of metal insert.Product, will with conductor terminals 6 after installation is complete at that time
It could be by signal when not forming completely enclosed wire chamber when only there is gap between the two with combining closely for metal insert 4
Pass to outside.Such structure can be used for being transformed existing general T type joint, is put into built-in sensors 2 and thermometric can be realized.
Fig. 3 is that 2 devices of built-in sensing are placed on 4 tail portion of metal insert, is cast in inside epoxy insulation.Such situation metal is embedding
The needs of part 4 produce the groove for putting built-in sensors 2, ensure that it is in equipotential volume, do not influence local discharging level.
