Wire box for relay protection test

Abstract

The invention relates to the technical field of wire boxes for experiments, and discloses a wire box for a relay protection test, which comprises a box body, communicated wire grooves are formed in the left side surface and the top surface of the box body, a first wire is arranged in each wire groove, and a second wire is arranged on the right side surface of the box body. The outer surface of the first line and the outer surface of the second line are sleeved with a first line arrangement plate and a second line arrangement plate respectively. According to the wire box for the relay protection test, communicated wire grooves are formed in the side faces and the front face of the box body, and a first wire is installed in the wire grooves in the side faces, so that the outer surfaces of the first wire and the second wire are sleeved with a first wire arrangement plate and a second wire arrangement plate respectively, and the outer surfaces of the first wire and the second wire are sleeved with limiting sleeves. After the wire box is used, the first wire arrangement plate and the second wire arrangement plate are pulled, so that multiple sets of first wires and second wires are rapidly and orderly arranged, the first wire arrangement plate and the second wire arrangement plate are used for adsorption and fixation, the operation convenience is improved, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of experimental wire boxes, in particular to a wire box for relay protection experiments. Background technique [0002] In the calibration of relay protection equipment, test lines are needed to connect the calibration instrument and the secondary circuit or photoelectric circuit of the equipment to be calibrated to transmit voltage, current signals or position signals. [0003] In the process of using the existing relay protection test wire box, due to the need to use the circuit in the test wire box to connect with the circuit to be tested and the detection equipment in the relay protection test, the test is carried out. In actual use, the test wire box There are too many wire ends, and with the entanglement of multiple wires after the test, it is difficult to arrange and store, and the use effect is not good. [0004] In addition, due to the lack of an effective fixing method for the existing relay prote...

Problems solved by technology

[0003] In the process of using the existing relay protection test wire box, due to the need to use the circuit in the test wire box to connect with the circuit to be tested and the detection equipment in the relay protection test, the test is carried out. In actual use, the test wire box There are too many wire ends, and with the entanglement of multiple wires after the test, it is difficult to arrange and store, and the use effect is not good

[0004] In addition, due to the lack of an effective fixing method for the existing relay protection test box during use, when the test box is placed flat on the platform, it is easy to produce a sliding offset, which makes the connected port break and increases the number of new The steps of connection reduce the connection efficiency, and when it is disconnected during the test, it is easy to affect the accuracy of the test data, and the use effect is poor

[0005] On the other hand, the existing test box for relay protection needs to carry the test box when it is used because the place where the test is required is not fixed. However, the existing test box is inconvenient to carry, and multiple groups of lines are exposed. , susceptible to wear and damage due to environmental influences, reducing the actual service life of the line, and poor usability
