Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary tools for electric power equipment, and in particular relates to a secondary test line storage bundler for power transformation. Background Art

[0002] The secondary equipment of a substation refers to the equipment that measures, monitors, controls and protects the operating conditions of primary equipment and systems. It mainly consists of relay protection devices, automatic devices, measurement and control devices, metering devices, automation systems and DC equipment that provides power to secondary equipment.

[0003] During the installation, routine maintenance and overhaul of secondary equipment in power system projects, in order to ensure the safe and stable operation of the power grid and the reliability of power supply, it is necessary to carry out pre-test and regular inspection of related equipment such as relay protection and automation. During the device debugging process, the secondary test line can be used as a transmission medium to send the analog quantity output by the tester to the device to be debugged. If it is left at random after the test, it is easy to cause the test line to be entangled and confused. Not only is it difficult to quickly find the required test line the next time it is used, but the test line may also be damaged due to entanglement or knotting, which not only affects work efficiency but may also lead to errors in experimental results. In view of this, the present utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a substation secondary test line storage bundler that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a substation secondary test line storage harness, including a storage box, and also including: a wire reel group, which is rotatably connected in the storage box, and both ends of the wire reel group extend out of the storage box; a plurality of through-openings are equidistantly provided on the wire reel group; a wire release opening used in conjunction with the through-opening is provided on the storage box; and a rubber ring is fixedly connected in the wire release opening.

[0006] In order to enable the storage limiter to be flexibly disassembled and assembled so as to replace the secondary test line, the storage box further includes two open shells used in conjunction with each other, and the two open shells are detachably connected by fixing bolts. The wire take-up reel group includes two sets of semicircular rotating shafts, semicircular separating plates and semicircular knobs. The two semicircular rotating shafts together constitute a rotating shaft and are rotatably connected in the middle position of the two open shells. Semicircular openings are equidistantly provided on the semicircular rotating shaft, and the semicircular openings on the two semicircular rotating shafts constitute a through opening. The semicircular separating plates are fixedly connected to both sides of the semicircular opening, and the semicircular knob is fixedly connected to one end of the semicircular rotating shaft extending out of the storage box.

[0007] In order to prevent the test line from being damaged due to a large bend, the through opening on the take-up reel assembly is further designed to be S-shaped.

[0008] In order to facilitate the rotation of the two semicircular shafts at the specified positions, further, a positioning semicircular ring is fixedly connected to the outer side of the semicircular separating plate, and a positioning groove used in conjunction with the positioning semicircular ring is opened on the inner wall of the open shell.

[0009] In order to keep the experimental harness in a taut state at all times, a friction layer is further provided on the inner wall of the positioning groove, the rubber ring and the through-opening.

[0010] In order to protect the connection end of the secondary test line when not in use, a protective sleeve for protecting the connection end of the test line is threadedly connected to the wire release port of the storage box.

[0011] After adopting the above technical solution, the utility model has the following beneficial effects compared with the existing technology: the utility model has a simple and compact structure, is easy to carry to the substation for use, can adjust the length of the secondary test line according to actual needs, and is also convenient for storing the entire line, avoiding the secondary test line from becoming cluttered and tangled, and facilitating subsequent use.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0021] Example 1:

[0022] Reference Figure 1-Figure 5 A substation secondary test line storage and bundler includes a storage box 1, and also includes: a wire take-up reel group 2, which is rotatably connected in the storage box 1, and both ends of the wire take-up reel group 2 extend out of the storage box 1; a plurality of through-holes 205 are equidistantly opened on the wire take-up reel group 2; a wire release opening 104 used in conjunction with the through-holes 205 is opened on the storage box 1; and a rubber ring 105 is fixedly connected in the wire release opening 104.

[0023] The storage box 1 includes two open shells 101 for use together, and the two open shells 101 are detachably connected by fixing bolts 102. The wire take-up reel group 2 includes two sets of semicircular rotating shafts 201, semicircular separating plates 202 and semicircular knobs 203. The two semicircular rotating shafts 201 together constitute a rotating shaft and are rotatably connected in the middle position of the two open shells 101. Semicircular openings are equidistantly provided on the semicircular rotating shafts 201. The semicircular openings on the two semicircular rotating shafts 201 form a through opening 205. The semicircular separating plates 202 are fixedly connected to both sides of the semicircular opening. The semicircular knob 203 is fixedly connected to one end of the semicircular rotating shaft 201 extending out of the storage box 1.

[0024] During assembly, the user first dismantles the cable storage device, and then inserts the secondary test line into the semicircular opening of one of the semicircular rotating shafts 201, and then inserts it into the semicircular opening of the other semicircular rotating shaft 201. Then, the two semicircular rotating shafts 201 can be combined into a rotating shaft, and then the rotating shaft can be clamped between the two open shells 101, and the secondary test line can be extended out of the open shell 101 through the wire release port 104. Then, the two open shells 101 are fixedly connected by fixing bolts 102 to form a storage box 1, and then the assembly of the secondary test line and the cable storage device can be completed. Then, the connecting ends are fixedly connected at both ends of the secondary test line, and then the two semicircular knobs 203 are turned to wind the experimental wiring harness around the rotating shaft.

[0025] When it is necessary to use a test harness to connect the secondary equipment and tester in the substation, the staff can pull the two ends of the secondary test line outward, and then the take-up reel group 2 will release the line. When the test harness is pulled out of the storage box 1 to a certain length, the two ends of the test harness can be connected to the secondary equipment and the tester respectively, and then the secondary equipment can be debugged through the tester. When the debugging operation is completed, the secondary test line is separated from the secondary equipment and the tester, and then the take-up reel group 2 can be rotated to wind the secondary test line, so that the test harness can be stored in the storage box 1 for protection.

[0026] Example 2:

[0027] Reference Figure 1-Figure 5 , a substation secondary test line storage bundler, which is basically the same as embodiment 1, further comprising: Figure 3 As shown, the through-opening 205 on the take-up reel assembly 2 is designed in an S-shape. When the two semicircular rotating shafts 201 are docked together and the middle part of the test line is clamped in the through-opening 205, it can not only ensure the stability of the connection between the test line and the two semicircular rotating shafts 201, but also when the test line is wound around the two semicircular rotating shafts 201, it can also prevent the test line from being damaged due to large bending, thereby effectively improving the protection effect of the test line.

[0028] A positioning semicircular ring 204 is fixedly connected to the outer side of the semicircular separating plate 202, and a positioning groove 103 is provided on the inner wall of the open shell 101 for use with the positioning semicircular ring 204. Through the setting of the positioning semicircular ring 204 and the positioning groove 103, the semicircular rotating shaft 201 can be positioned, thereby facilitating the rotation of the two semicircular rotating shafts 201 at the specified position.

[0029] Friction layers are provided on the inner walls of the positioning groove 103, the rubber ring 105 and the through-hole 205. By providing the friction layer in the positioning groove 103 and the rubber ring 105, the test line can always be kept in a taut state, avoiding the problem of inconsistent lengths at both ends of the test line due to looseness and inconsistency at both ends, thereby affecting the subsequent line winding stability. At the same time, when the test line cup is pulled out for use, the stability between the test line and the cable storage device can also be guaranteed. By providing the friction layer in the through-hole 205, the test line can be more firmly clamped in the through-hole 205 formed between the two semicircular rotating shafts 201, and the uniformity of the lengths of the two ends of the test line can be further improved.

[0030] Example 3:

[0031] Reference Figure 1-Figure 5 , a substation secondary test line storage bundler is basically the same as Example 2, and further: a protective sleeve 106 for protecting the test line connection end is threadedly connected at the wire release port 104 of the storage box 1. Through the setting of the protective sleeve 106, after the test line is stored in the storage box 1, the connection end of the test line will be stuck at the wire release port 104 of the storage box 1, and then by sleeved on the test line connection end and threadedly connected to the protective sleeve 106 at the wire release port 104, the test line connection end can be covered, which effectively improves the overall protection effect of the test line after the test line is stored and bundled.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
