Abstract

The utility model provides a short circuit seal used for plugging in a current test terminal. The short circuit seal comprises a plurality of contact pins and a wire, wherein the contact pins are provided with structures matched with the current test terminal; and the contact pins are connected together through the wire. By adopting the short circuit seal used for plugging in a current test terminal provided by the utility model, the short circuit seal adopts the structure that the contact pins are connected with the wire, the phenomenon of unstable crimp connection easily occurs because the wire is required to be plugged in the terminal once the wire is adopted to perform short circuit sealing, the secondary short circuit phenomenon can not be thoroughly avoided; therefore, the short circuit phenomenon can be thoroughly eliminated due to the adoption of the short circuit seal.

Description

The short sealing of current testing terminal is used to peg graft
Technical field
The utility model relates to a kind of short sealing of the current testing terminal that is used to peg graft.
Background technology
Current transformer is low pressure and the distribution of high-tension electricity and the equipment of transmission of electricity fundamental sum indispensability that is widely used in prior art, is usually used in metering and the protection and other the automatic control etc. of electric power.The current transformer that is used for electric power system at present, its primary winding is serially connected in the test line, and secondary coil is connected in series various instrument or forms secondary circuit with the various relays of protection system control loop etc.Under the normal condition, the secondary side of current transformer approaches short-circuit condition.In case secondary circuit is opened a way, primary winding will all be used for excitatory, make iron core be in the height saturation condition, and core loss and temperature are sharply increased, cause secondary coil can respond to very high voltage, jeopardize various device and the operator safety of string at secondary circuit.Therefore, no matter be in the actual motion or check and accept commissioning test at the scene or maintenance after test in, all forbid the secondary circuit of current transformer that the open circuit phenomenon takes place.In the prior art, use, adopt lead to lack envelope usually, the end of a thread need be inserted in the terminal, tighten with screwdriver in order to guarantee that secondary circuit the phenomenon of opening a way can not occur.
The inventor finds that there are the following problems at least in the prior art: owing to adopt lead to lack envelope, the end of a thread need be injected the terminal the inside, the easy so unreal phenomenon of crimping that occurs can't thoroughly be avoided the generation of second short circuit phenomenon.
The utility model content
The utility model aims to provide a kind of short sealing of the current testing terminal that is used to peg graft, can solve owing to adopt lead to lack envelope, the end of a thread need be injected terminal the inside, the easy so unreal phenomenon of crimping that occurs can't thoroughly be avoided the problems such as generation of second short circuit phenomenon.
In embodiment of the present utility model, a kind of short sealing of the current testing terminal that is used to peg graft is provided, comprising: a plurality of contact pins have the structure that matches with the current testing terminal; Lead, it links together a plurality of contact pins.
Preferably, lead is connected in series a plurality of contact pins.
Preferably, lead is many, and welds together in the middle part of it, and the two ends of every lead connect contact pin respectively.
Preferably, the multiple conducting wires outside has insulating material.
Preferably, the weld outer setting has adhesive plaster or sleeve pipe.
Preferably, a plurality of contact pins are eight.
Preferably, contact pin is an aviation plug.
Because adopt short sealing according to the current testing terminal that is used to peg graft of the present utility model, it has the structure of contact pin and lead connection, so overcome owing to adopt lead to lack envelope, the end of a thread need be injected the terminal the inside, the easy so unreal phenomenon of crimping that occurs, can't thoroughly avoid the problem of the generation of second short circuit phenomenon, and then reach the effect of thorough elimination second short circuit.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the structure according to an embodiment of the present utility model;
Fig. 2 has schematically shown the structure according to another embodiment of the present utility model.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Fig. 1 has schematically shown the structure according to an embodiment of the present utility model, in conjunction with referring to Fig. 2, as shown in the figure, in embodiment of the present utility model, a kind of short sealing of the current testing terminal that is used to peg graft is provided, and comprising: a plurality of contact pins 1 have the structure that matches with the current testing terminal; Lead 2, it links together a plurality of contact pins 1.During use, a plurality of contact pins are inserted the current testing terminal, can effectively avoid in process of the test, occurring secondary loop of mutual inductor open circuit phenomenon.Employing is according to the short sealing of the current testing terminal that is used to peg graft of the present utility model, it has the structure of contact pin and lead connection, overcome owing to adopt lead to lack envelope, the end of a thread need be injected the terminal the inside, the easy so unreal phenomenon of crimping that occurs can't thoroughly be avoided the problem of the generation of second short circuit phenomenon, and then has reached the effect of thorough elimination second short circuit, and it is convenient and swift, safe and reliable.
As shown in Figure 1, preferably, lead 2 is connected in series a plurality of contact pins 1.Connecting contact pin row made from lead 1, all be conducting between each contact pin 1, and conducting is good, effective like this generation of avoiding the testing terminal second short circuit, and also convenient and swift like this, safe and reliable.
As shown in Figure 2, preferably, lead is many, and welds together in the middle part of it, and the two ends of every lead connect contact pin 1 respectively.Like this, be convenient to operation, safe and reliable.
Preferably, multiple conducting wires 2 outsides have insulating material.Like this, safe and reliable, and good looking appearance.
As shown in Figure 2, preferably, the weld outer setting has adhesive plaster or sleeve pipe 4.Like this, easy to use, and have the good insulation performance effect, safe and reliable.
As Fig. 1 and shown in Figure 2, preferably, a plurality of contact pins 1 are eight.Like this, the quantity of contact pin 1 is moderate, and certainly, its quantity can increase and decrease arbitrarily, with the quantity of Pass Test terminal.
Preferably, contact pin 1 is an aviation plug.Like this, the pin diameter of aviation plug just in time matches with the diameter of terminal, and is very firm after the grafting.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
Because adopt short sealing according to the current testing terminal that is used to peg graft of the present utility model, it has the structure of contact pin and lead connection, so overcome owing to adopt lead to lack envelope, the end of a thread need be injected the terminal the inside, the easy so unreal phenomenon of crimping that occurs can't thoroughly be avoided the problem of the generation of second short circuit phenomenon, and then has reached the effect of thorough elimination second short circuit, and it is easy to use, and is safe and reliable.
