Abstract

The utility model provides a pole-tower groundwire-connecting system for reducing electric-energy loss, which comprises pole towers, ordinary groundwires and optical-fiber composite overhead groundwires, wherein the ordinary groundwires and the optical-fiber composite overhead groundwires are arranged at both sides of the pole towers, each ordinary groundwire and each optical-fiber composite overhead groundwire are respectively crosswise arranged at both sides of each pole tower through insulator strings and strain clamps, and an insulator is arranged beside the strain clamp on each ordinary groundwire. Because each ordinary groundwire and each optical-fiber composite overhead groundwire are respectively crosswise and fixedly arranged at both sides of each pole tower of the pole-tower groundwire-connecting system through the insulator strings and strain clamps, the ordinary groundwires and the optical-fiber composite overhead groundwires are insulated through the insulator strings in a segmented mode, and the ordinary groundwires and the optical-fiber composite overhead groundwires are grounded only through the strain clamps and the pole towers, so that the generation of groundwire circular current is reduced, the loss is greatly lowered, and the cost of electrical-power production is lowered.

Description

A kind of shaft tower ground wire connected system

Technical field

The utility model relates to a kind of connected system, especially a kind of shaft tower ground wire connected system.

Background technology

When transmission line normally moves, can flow through certain induced current in the ground wire, thereby cause electric energy loss.The proportion in the electrical network total losses of the loss of ground wire in the past is little, and the concern that receives is less, but along with the continuous development of electrical network and the continuous expansion of transmission capacity, the loss that ground wire causes in the electric power system is also increasing.Present earthed circuit adopts by tower ground connection mostly; Promptly two ground wires are fixed on the both sides of shaft tower through wire clamp; The adjacent two ground wire junctions of every side are fixed on the shaft tower through wire clamp, such structure be exactly common ground wire and optical cable ground wire all by tower ground connection, cause huge electric energy loss.

The utility model content

The purpose of the utility model provides a kind of shaft tower ground wire connected system that reduces electric energy loss.

Realize a kind of shaft tower ground wire connected system of the utility model purpose; Comprise shaft tower, be arranged on the common ground wire and the OPGW of said shaft tower both sides; Said common ground wire and OPGW are connected the both sides of each said shaft tower respectively across through insulator string and strain clamp, the strain clamp next door on the said common ground wire is provided with insulator.

The beneficial effect of the utility model is: because common ground wire and OPGW are to be fixed on the shaft tower through insulator string and strain clamp across; Common like this ground wire and OPGW just have been insulated the substring graded insulation; Only passing through strain clamp and tower grounding; Thereby reduced the generation of ground wire circulation, reduced loss significantly, reduced the cost of electrical production.

Description of drawings

Fig. 1 is the structural representation of a kind of tower grounding connected system of the utility model.

Embodiment

The embodiment of the utility model is following.

As shown in Figure 1; A kind of shaft tower ground wire connected system of the utility model; Comprise shaft tower 4, be arranged on the common ground wire 2 and the OPGW 1 of said shaft tower 4 both sides; Said common ground wire 2 and OPGW 1 are connected the both sides of each said shaft tower 4 respectively across through insulator string 6 and strain clamp 5, strain clamp 5 next doors on the said common ground wire 2 are provided with insulator 7.

A kind of tower grounding connected system of the utility model; Because common ground wire 2 is to be fixed on the shaft tower 4 through insulator string 6 and strain clamp 5 across with OPGW 1; Common like this ground wire 2 just has been insulated substring 6 graded insulations with OPGW 1, is only passing through strain clamp 5 and shaft tower 4 ground connection, thereby has reduced the generation of ground wire circulation; Reduce loss significantly, reduced the cost of electrical production.

Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection range that claims of the utility model confirm.

Claims

1. shaft tower ground wire connected system; Comprise shaft tower, be arranged on the common ground wire and the OPGW of said shaft tower both sides; It is characterized in that: said common ground wire and OPGW are connected the both sides of each said shaft tower respectively across through insulator string and strain clamp, and the strain clamp next door on the said common ground wire is provided with insulator.
