Description
Technical Field
The utility model belongs to the technical field of electric and specifically relates to an insulating stopper of sensor type is related to.
Background
In a 0.6-35 kV medium and low voltage power cable distribution system, the contact resistance of a joint of a cable joint is increased due to long-time running aging, improper installation and the like, so that the temperature is increased. When the temperature rises to a certain degree, the mechanical strength and the electrical strength of the equipment are reduced, and the short circuit of the electrical equipment can be caused in severe cases, even the damage of the equipment is caused, and the safe operation of a power grid is seriously threatened. The insulating plug is a cable accessory which is arranged at the tail end of the cable joint and plays the roles of plugging, insulating and sealing, and the bolt in the insulating plug is tightly connected with the conductive part, so that the temperature of the insulating plug can visually reflect the temperature of a conductor in electrical equipment.
The existing method for measuring the temperature of the insulating plug comprises infrared temperature measurement, wherein the infrared temperature measurement is carried out in a manual measurement mode, the measured temperature is the surface temperature, the box cannot be opened during the operation of electrical equipment, generally, infrared rays penetrate through a glass window for measurement, the measurement error is large, and the temperature of an inner conductor cannot be accurately reflected; install temperature sensor in the insulating stopper outside in addition, read the temperature through being connected temperature sensor and display, the temperature that adopts this method to detect receives the influence of other outside equipment very easily, can lead to the circuit in a jumble moreover, is unfavorable for maintenance and maintenance, also has to place temperature sensor in the insulating stopper inside, reads temperature signal through wireless transmission's mode, but the ubiquitous inner structure is unreasonable, leads to the problem that product partial discharge value is on the high side.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned technical problem, provide an insulating stopper temperature measurement structure that can accurate measurement cable accessories inner conductor temperature, installation be convenient, be difficult for receiving external disturbance. The method is mainly realized by the following technical scheme:
the utility model provides an insulating stopper of sensor type, its characterized in that, includes an insulating stopper body that has the cavity, is equipped with an inner wall in the cavity and is equipped with the screwed sealed cowling, and the sealed cowling bottom is equipped with screw-thread fit's closing plate, and the sealed cowling is equipped with a temperature sensor, the one end contact of temperature sensor one end and spring, the other end and the closing plate contact of spring, the other end of temperature sensor through with the screw fixation of sealed cowling screw-thread fit in the sealed cowling.
At foretell sensor type insulating plug, be equipped with a II type mounting in the sealed cowling, temperature sensor sets up in II type mounting, II type mounting one end and the one end contact of spring, the other end of II type mounting is through the fix with screw in the sealed cowling with sealed cowling screw-thread fit.
In the sensor type insulating plug, the other end of the sealing cover is provided with the I-shaped sealing element, one end of the I-shaped sealing element is provided with a thread matched with the sealing cover in a threaded manner, the middle part of the I-shaped sealing element is provided with a groove for placing a screw, and the other end of the temperature sensor is in contact with one end of the I-shaped sealing element provided with the thread.
Therefore, the utility model has the advantages of as follows: 1. the temperature of the conductor in the cable joint can be directly measured; 2. the temperature signal is transmitted by the sensor in a wireless way, so that the temperature sensor is stable and convenient; 3. the internal structure is reasonable, the electric field can be effectively uniform, and the local discharge value of the product is low; 4. the high-pressure box is not opened, and the safety and the reliability are realized.
