Abstract
The utility model relates to a detection connector for an end screen of a transformer. The detection connector consists of a polytetrafluoroethylene connector, a conductive rod, a metal pressing block, a spring, an outgoing line connector, an end screen cover and a waterproof cable connector, wherein the front end of the polytetrafluoroethylene connector is fixed with end screen equipment of a transformer bushing, and the rear end of the polytetrafluoroethylene connector is fixed on the end screen cover; the outgoing line connector is fixed at the axial center position of the rear end of the polytetrafluoroethylene connector, the spring and the metal pressing block are arranged at a central shaft of the polytetrafluoroethylene connector, the rear end of the spring is in contact with the outgoing line connector, and the front end of the spring is compressed on the metal pressing block; the metal pressing block is fixed with the conductive rod; and the waterproof cable connector is arranged at the rear end of the end screen cover to realize moistureproof sealing. The detection connector disclosed by the utility model can solve the problems that the traditional product is easy to be affected with damp, cannot meet the online monitoring requirements and is complex in structure and high in cost.
Description
Technical field
The utility model relates to screen detection technique field, bushing shell for transformer end, specifically is a kind of transformer end screen detection tabs.
Background technology
Along with the scale of electrical network constantly enlarges, the uncertain factor and the potential risk that influence safe operation of power system increase thereupon, thereby the user is increasingly high to the safe reliability and the quality requirements of electric power supply.Guaranteeing safe operation of power system, is the major subjects of Chinese electrical network research and development.Power transformer is one of visual plant in the electric system; Sleeve pipe is as an important accessory of transformer; Cause one of principal element of transformer fault often; Bushing shell for transformer is carried out online detection, can find its insulation defect early, confirm state of insulation, have very important significance for improving system's operational reliability.Have now sleeve pipe is carried out online test method employing external current sensor senses, this method is owing to receive the influence of current sensor external environment condition of living in, and detected data often have certain deviation, cause detected data inaccurate.And the existing product complex structure, with high costs, and make moist easily, can not satisfy the requirement of on-line monitoring.
The utility model content
The purpose of the utility model provides a kind of transformer end screen detection tabs, and it can solve the reliability requirement that existing end screen detection tabs can not satisfy on-line monitoring.
The utility model solves the problems of the technologies described above through following technical scheme: a kind of transformer end screen detection tabs is made up of teflon joint, conducting rod, metal briquetting, spring, pinout connector, end screen cover and water-proof cable joint.Wherein, the last screen equipment of teflon joint front end and bushing shell for transformer is fixed, and the rear end is fixed on the screen cover of end; Pinout connector is fixed on the shaft core position of teflon joint rear end through screw thread, and spring and metal briquetting place the central shaft position of teflon joint, and spring rear end contacts with pinout connector, and front end is pressed on the metal briquetting; Metal briquetting and conducting rod are fixed; The water-proof cable joint is installed in the rear end of end screen cover, realizes moisture seal.
Said spring and metal briquetting are successively put into the central shaft position of teflon joint, fix with the conducting rod of bottom shielding of bushing again.
The outstanding advantage of the utility model is:
1, it is inner that the signal cable line is closed in end screen cover, draws through water-proof cable, can be effectively moistureproof.
2, compact to design, with low cost, help extensive on-the-spot the popularization.
3, simple in structure, easy to process, and change easy for installation.
Description of drawings
Fig. 1 is the structural representation of the described transformer of the utility model end screen detection tabs.
Embodiment
Below through accompanying drawing and embodiment the technical scheme of the utility model is further specified.
As shown in Figure 1, the described transformer of the utility model end screen detection tabs is made up of teflon joint 1, conducting rod 2, metal briquetting 3, spring 4, pinout connector 5, end screen cover 6 and water-proof cable joint 7.Concrete structure and connected mode are:
The last screen equipment of teflon joint 1 front end and bushing shell for transformer is fixed, and the rear end is fixed on the end screen cover 6, and pinout connector 5 is fixed on the shaft core position of teflon joint 1 rear end through screw thread; Spring 4 and metal briquetting 3 place the central shaft position of teflon joint 1; Spring 4 rear ends contact with pinout connector 5, and front end is pressed on the metal briquetting 3, and metal briquetting 3 is fixing with conducting rod 2; Water-proof cable joint 7 is installed in the rear end of end screen cover 6, realizes moisture seal.
Concrete mounting means is:
2. after signal cable being connected to the rear end of pinout connector 5, draw from water-proof cable joint 7;
3. water-proof cable joint 7 is through being sealingly clamped on the end screen cover 6;
4. behind the outgoing cable totally enclosed end screen cover 6 is fixed on the teflon joint 1, realizes cable and outside moistureproof the isolation;
5. spring 4 and metal briquetting 3 are successively put into the central shaft position of teflon joint 1, fixing with the conducting rod 2 of bottom shielding of bushing again;
6. compress behind the conducting rod 2 on the corresponding interface that is fixed on bushing shell for transformer end screen foremost with teflon joint 1, can carry out end and shield current detecting.
After circuit has connected, just can signals collecting be shielded at the end and upload.
Claims (2)
1. a transformer end screen detection tabs is characterized in that, this joint is made up of teflon joint, conducting rod, metal briquetting, spring, pinout connector, end screen cover and water-proof cable joint; Wherein, the last screen equipment of teflon joint front end and bushing shell for transformer is fixed, and the rear end is fixed on the screen cover of end; Pinout connector is fixed on the shaft core position of teflon joint rear end through screw thread; Spring and metal briquetting place the central shaft position of teflon joint, and spring rear end contacts with pinout connector, and front end is pressed on the metal briquetting; Metal briquetting and conducting rod are fixed, and the water-proof cable joint is installed in the rear end of end screen cover.
