Abstract
The utility model provides an intelligent electric connector for a power transformer, and aims to solve the technical problems that an existing small casing pipe used for connecting the inside of a transformer and outside wires has defects that occupied space is large, oil can leak and the like, and therefore intelligent management of the power transformer can not be realized and the like. The electric connector is formed by connecting a square flange with a cylinder in a threaded mode, a glass sintered insulator is arranged inside the cylinder, and a blade terminal group is distributed on the glass sintered insulator to form the whole electric connector which is fixed on a flange on the wall of a transformer box. The electric connector and the flange are sealed with a sealing pad. The intelligent electric connector for the power transformer has the advantages that due to the fact that the electric connector is used as a line outlet method of a secondary line inside the transformer, the connection between the inside of the transformer and the outside wires is achieved, transmission of current and voltage in the transformer is guaranteed, and the effects that size is small, oil sealing performance is good, the transformer does not need to be dismounted and mounted in a test, and operation is more convenient and fast are achieved; and through an intelligent module, the transformer can be monitored, and the purpose that people are not needed for watching the transformer is achieved.
Description
Technical field:
The utility model relates to a kind of electric connector, relates in particular to a kind of a kind of intelligent electric power transformer electric connector for intelligent electric power transformer and the inner outlet method of transformer.Be mainly used in aerospace field.
Background technology:
At present a lot of users require more and more higher to the quality of power supply, bring the phenomenon of very large loss for avoiding having a power failure suddenly to the user, and some transformer is distributed in environment abominable area or high Mountain area, and manpower arrives inconvenient, and transformer is patrolled and examined and safeguarded also inconvenient.Therefore want to realize the power transformer intelligent management, solve the transformer secondary line from the problem of fuel tank internal outlet with regard to need, existing transformer is inner to use small casing usually with being connected of outer lead, and not only the volume that takies of existence is large, and has the defective such as leakage of oil.
Summary of the invention:
Existing transformer is inner to use small casing with being connected of outer lead to the utility model in order to solve, exist the volume that takies large, the defective such as leakage of oil again, can't realize the technical problems such as power transformer intelligent management, provide a kind of electric connector that adopts to realize that the transformer secondary line is from the technical scheme of fuel tank internal outlet:
Intelligent electric power transformer electric connector, this electric connector is threaded with cylinder by square flange and combines, be equipped with the glass sintering insulator in described cylinder interior, be furnished with one group of lug plate at described glass around the punishment of junction isolation body, form a whole electric connector, and be fixed on the transformer box wall flange; Between electric connector and flange, adopt the sealing gasket sealing.
Characteristics of the present utility model and beneficial effect: owing to adopt electric connector as the outlet method of transformer inside secondary line, having overcome prior art uses small casing to exist the volume that takies large, the defective of leakage of oil again, both satisfied transformer inner with being connected of outer lead, guarantee again the transmission of the current/voltage of transformer, also realized the sealing of transformer oil; Realized the low-voltage product, adopted plug-in cable connected mode and transformer body to go between easy to connect and reduce insulation distance, made to rise that transformer overall dimension is dwindled and the purpose that reaches fuel-efficient and dwindle volume of transformer; When having guaranteed transformer test, it is more convenient, quick to need not dismounting; The operational inconvenience and the worry that have needed the dismounting to bring when having overcome original structure owing to test.Be in particular in:
1, electric connector adopts the flange on square flange and the oil tank of transformer to fix, and around the flange sealing gasket is arranged, and this kind mode has guaranteed the sealing of transformer oil;
2, the electric connector brace adopts duck tongue type brace, and this shape brace has guaranteed that the contact-making surface of lug plate can fully contact, and has also increased contact area simultaneously, guarantees the firm transmission of current/voltage;
3, electrical connection device lug plate spacing is 10mm, and withstand voltage is AC5KV, and this kind is withstand voltage to have guaranteed that electric connector need not remove electric connector when transformer test.
4, electric connector adopts the plug-in connected mode, and is more convenient during wiring, quick;
5, electric connector adopts plug-in cable connected mode and transformer body to go between easy to connect and reduces insulation distance, because it is little to take up room, the product of being more convenient for is arranged.

Embodiment:
Referring to Fig. 1-Fig. 3, intelligent electric power transformer electric connector, this electric connector 1 is threaded with cylinder 3 by square flange 2 and combines, be equipped with glass sintering insulator 4 in described cylinder 3 inside, be furnished with one group of lug plate 5 at described glass around 4 punishment of junction isolation body, form a whole electric connector, and be fixed on the transformer box wall flange; Adopt the sealing gasket sealing between electric connector and flange, this kind mode has guaranteed the sealing of transformer oil.
The lug plate 5 of described electric connector 1 adopts duck tongue type brace, and this shape brace has guaranteed that the contact-making surface of lug plate can fully contact, and has also increased contact area simultaneously, guarantees the firm transmission of current/voltage.
The spacing of the lug plate 5 of described electric connector 1 is 10mm, and withstand voltage is AC5KV, and this kind is withstand voltage to have guaranteed that electric connector need not remove electric connector when transformer test.
Send the inner signal of telecommunication that gathers of transformer to outside intelligent object by cable by described electric connector 1.
Described electric connector 1 adopts the plug-in connected mode to be connected with inside and outside, and is very convenient during wiring.
Referring to Fig. 4-Fig. 6, during installation, electric connector is installed on the transformer sidewall, with the sealing gasket sealing, inner lead links to each other with the electric connector seat on every side, and external cabling is connected on the electrical connector plug, transformer is inserted into plug on the socket when assembling, has connected together with transformer integral body like this.
During use, go out voltage and current signal by the sensor sensing in transformer inside, from low-voltage lead, gather the low-tension current signal, by electric connector 1 the intelligent object of electric signal transmission to the transformer outside, intelligent object is converted into radio signal transmission to these signals of telecommunication to central control room internal information processing platform again, then make corresponding processing according to these data, transformer fault is processed among rudiment, guaranteed the continuity reliability of power supply, realized to the monitoring of transformer that nobody holds to keep.
The inner signal of telecommunication that gathers of transformer sends intelligent object to by cable, cable routing transformer inside links to each other with the external cable line by electric connector, adopt electric connector to be herein because oil-immersed type transformer inside is full of transformer oil, therefore sealing is a large problem, the employing electric connector has not only solved oily sealing problem but also has solved the problem of current/voltage output, the electric connector volume is little in addition, the inside and outside connection adopts wire to be welded on the lug plate, and being connected the employing plug-in with the outside, this makes connection/dismounting all very convenient.
