Background technology
With continuing to develop for electrical equipment, more and more higher required equipment test condition, and test number (TN) is also increasingly
More for example, when doing the experiment such as protective calibration, ac voltage withstanding, experiment could be met by generally requiring many electric currents, voltage test line
It is required that, relay protection is as research electric power system fault and the unusual service condition for jeopardizing safe operation, to inquire into the anti-thing of its countermeasure
Therefore automation measure, power system and its element are mainly protected with the relay for having contact in its evolution, is allowed to exempt from
Infringement, the connective stability of existing p-wire and measured object is poor, easily disconnects, influence equipment test effect and test efficiency.
The content of the invention
It is stable there is provided a kind of attachment structure it is an object of the invention to make up the deficiencies in the prior art part, examination can be improved
Test the relay protection test wire connection structure of effect and test efficiency.
The purpose of the present invention is realized by following technological means：
A kind of relay protection test wire connection structure, including p-wire and be connected with p-wire both side ends test contact
Joint, joint be used for be connected with the instrument connection of equipment under test, it is characterised in that：Also include U-shaped fastener, spring and two limits
Position plate, p-wire is located in the opening of U-shaped fastener through setting in the middle part of spring and U-shaped fastener, joint, the U-shaped fastener
It is connected by spring with joint rear end, the both sides of U-shaped fastener are provided with positioning hole；Two described limiting plates are set with tested
It is symmetrical centered on standby instrument connection, it is equipped with the locating piece matched with U-shaped fastener positioning hole, U on the outside of each limiting plate
Type fastener and limiting plate realize that clamp is positioned by positioning hole and locating piece, and the end that limiting plate is connected with equipment under test is provided with
Side plate, side plate is connected by bolt with equipment under test.
Moreover, one end top pressure of described spring is on U-shaped fastener, other end top pressure is set by joint rear end
On boss.
Moreover, described U-shaped fastener and limiting plate are made of flexible plastic material.
Advantages and positive effects of the present invention are：
1st, present apparatus reasonable in design, when p-wire joint and equipment under test instrument connection connect when, can pass through
Positioning hole and locating piece realize being connected for U-shaped fastener and two limiting plates, while the junction of joint and instrument connection can
See, ensured the attachment structure stability of p-wire, improved test effect and test efficiency.
2nd, the p-wire in the present apparatus is through setting in the middle part of spring and U-shaped fastener, and U-shaped fastener by spring with connecing
Head rear end connection, this design can make U-shaped fastener carry out the movement and rotation of small range by the deformation of spring, be adapted to
The instrument connection connection of joint and different depth.
3rd, the present invention have that simple in construction, easily fabricated, easy to use, practical, manufacturing cost is low, light quality in
Many advantages, such as carrying, it is adapted in power industry popularization and application.
