Description

Special threading tool for substation secondary cables

technical field

The utility model belongs to the technical field of electric power system maintenance equipment, and in particular relates to a special threading tool for secondary cables of substations.

Background technique

During maintenance in the power industry, it is often necessary to pass secondary cables through switch cabinets, protective screens and terminal boxes. In the prior art, a short cable is usually used for reverse pre-threading, and then the short cable and the cable to be threaded are bound in parallel with cable ties, and the cable to be threaded is brought out with the short cable to complete the threading. Due to the complex structure of this part, many corners and corners, and narrow space, the secondary cable threading is extremely inconvenient, and the outer insulation of the cable is easily damaged during the threading process. However, when the number of secondary cables is large, threading is difficult, takes a long time, requires more personnel to cooperate, and seriously affects production efficiency. In the actual operation process, because the parallel binding of cables is easy to jam at the corners and corners, the cable tie is easy to break during the traction process, and the place where it is worn is dark and difficult to see, resulting in a high threading failure rate and low production efficiency. . the

Invention content

The purpose of the utility model is to solve the technical problems in the prior art that the secondary cable threading is easy to jam, fall off and unclear, and provide a special threading tool for the secondary cable of the substation. the

In order to achieve the above purpose, the special threading tool for the secondary cable of the utility model substation includes a universal hose, a connecting piece and a tightening piece. socket and hose connection plug; the middle of the connecting piece is provided with a luminous piece, and the two ends of the connecting piece are respectively provided with connecting jacks; one end of the fastening piece is provided with a tightening plug, and A conical piece is provided; the conical piece is connected with the cable through a tightening sleeve. the

The shape and size of the hose connecting plug and the tightening plug of the tightening part match with the connecting socket of the connecting part respectively. the

The plug and the jack are of threaded connection structure. the

The universal hose can be used in multiple connections with each other as required. the

The universal hose in the utility model can be bent arbitrarily, and it is easy to thread in various positions. The tapered part can tighten the cable head to avoid jamming during the threading process caused by parallel binding. The light-emitting part is installed in the connecting part. Can be illuminated. The utility model is suitable for pulling and threading secondary cables in multiple positions such as switch cabinets, protective screens and terminal boxes. the

Detailed ways

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model substation secondary cable special-purpose threading tool includes a universal hose 2, a connecting piece 4 and a tightening piece 8, and the two ends of the universal hose 2 are respectively A matching hose connection socket 1 and a hose connection plug 3 are provided; a light-emitting member 5 is provided in the middle of the connector 4, and a connection jack 6 is respectively provided at both ends of the connector 4; the tightening member One end of 8 is provided with a tightening plug 7, and the said tightening part 8 is provided with a conical part 9; the said conical part 9 is connected with the cable 11 through a tightening sleeve 10; said hose connects the plug 3 and the tightening part The shape and size of the tightening plug 7 coincide with the connecting jack 6 of the connector respectively; the plugs 3, 7 and the jacks 1, 6 are threaded and threaded structures; the universal hose 2 can be multiple as required connected to each other.

The insulated solid universal hose 2 can be bent arbitrarily, and multiple hoses with threads can be connected and used. The tapered part is used to fix the cable head, and the cable head can be received in the screwing part. The minimum tightening diameter of the terminal tightening part is 1 cm, and the maximum tightening diameter is 3 cm. After tightening, it can bear a weight of 30 kg without loosening. The tightening part 8 and the universal hose 2 are connected by a rectangular connecting part 4 with rounded corners. The rectangular connector with rounded corners is made of transparent plastic, contains a luminous lighting element, and is powered by a button battery. the

Before threading, first connect the universal hose 2 and the connecting piece 4 of the rounded rectangle 2, pass it downwards from the upper opening of the threaded position, then tighten and fix the cable with the terminal tightening piece 8, and connect the rounded rectangular connecting piece , and then pull out the universal hose from the upper mouth of the threaded position, bring out the cable, and complete the threading. the
