Abstract
The utility model relates to a fixing device for a secondary side over-voltage protector of a current transformer. The fixing device comprises a display panel and a mainboard. One plug is arranged on each of the two sides of the mainboard. Sockets are arranged at corresponding positions of the display panel. The plugs are plugged in and separated from the sockets. Rigid contact pins are distributed on the plugs. Compared with the prior art, the fixing device for the secondary side over-voltage protector of the current transformer does not damage the internal structure of the protector, realizes detachable fixed connection, facilitates the subsequent maintenance of a circuit board, and has a simple structure and good actual using effects.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of Current Transformer Secondary side overvoltage protection device fixture.
Background technology
Existing current transformer is widely used in the electric power system.In the operate as normal, the Current Transformer Secondary side is in approximate short-circuit condition, and output voltage is very low.In the situation of actual motion; If when a winding flows through abnormal current; As producing thunder-strike current, resonance current, electric capacity charging current, inductance starting current etc. in the circuit, also all can produce the overvoltage of thousands of volts even volts up to ten thousand at secondary side, not only insulation works the mischief to secondary side for this; Can cause also when serious that current transformer is too drastic and burn, even jeopardize staff's life security.
Current Transformer Secondary side overvoltage protection device internal structure more complicated, it is that screw is fixed that common protector connects fixed form.Screw is fixing twists when too loose, and the protector environmental suitability is relatively poor, and when slightly impact shock being arranged, screw is prone to come off; During overtorquing, easy again injury protection device internal circuit board also is unfavorable for follow-up installation and maintenance.
Summary of the invention
The deficiency that the utility model exists to prior art just provides a kind of Current Transformer Secondary side overvoltage protection device fixture.The described Current Transformer Secondary side of the utility model overvoltage protection device fixture comprises: display panel and mainboard, and the both sides of described mainboard are provided with plug, are provided with socket in the corresponding position of display panel, and plug and socket plugs together and separates.
Be distributed with the rigidity contact pin on the described plug.
The described Current Transformer Secondary side of the utility model overvoltage protection device fixture compared with prior art, not only can not be damaged to the protector internal structure; And realized dismountable fixed connection; Make things convenient for the maintenance of subsequent conditioning circuit plate, it is simple in structure, and practical effect is good.
Description of drawings
Fig. 1 is the described Current Transformer Secondary side of a utility model overvoltage protection device fixture mounting structure sketch map;
Fig. 2 is the described Current Transformer Secondary side of a utility model overvoltage protection device fixture sketch map;
Wherein:
1-display panel, 2-mainboard, 3-plug, 4-socket.
Embodiment
To combine concrete embodiment that the content of the utility model is described below.
As shown in Figure 1, be the described Current Transformer Secondary side of the utility model overvoltage protection device fixture mounting structure sketch map, Fig. 2 is its fixture sketch map.Protector mainly comprises display panel 1 and mainboard 2.Display panel 1 is mounted and fixed on the mainboard 2.Existing mounting means is with display panel 1 both sides lengthening, and to be provided with the hole.Be screwed in mainboard 2 after utilizing screw to pass this hole.This mode of installing and fixing is easy to damage display panel 1 and mainboard 2, causes Current Transformer Secondary side overvoltage protection device operational failure.
In order to eliminate this hidden danger; The described Current Transformer Secondary side of the utility model overvoltage protection device is provided with plug 3 in the both sides of mainboard 2; Be provided with socket 4 in display panel 1 corresponding position; Be distributed with some rigidity contact pins on the plug 3, utilize rigidity contact pin and socket 4 closely to plug together together.Be in the same place when plug 3 closely cooperates with socket 4, display panel 1 also plugs together with mainboard 2 is in the same place.When follow-up maintenance need be opened display panel 1 and mainboard in 2 minutes, firmly upwards pull up display panel 1, plug 3 separates with socket 4, realizes separating of display panel 1 and mainboard 2 like this.
The described Current Transformer Secondary side overvoltage protection device fixture of the utility model; Be to be provided with plug 3, and be provided with socket 4, likewise in display panel 1 corresponding position in the both sides of mainboard 2; Also socket 4 can be set in the both sides of mainboard 2; And plug 3 is set in display panel 1 corresponding position, and can realize the purpose of the utility model equally, this does not break away from the essence of the utility model.
The described Current Transformer Secondary side of the utility model overvoltage protection device fixture compared with prior art, not only can not be damaged to the protector internal structure; And realized dismountable fixed connection; Make things convenient for the maintenance of subsequent conditioning circuit plate, it is simple in structure, and practical effect is good.
