Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to electrical equipment, and particularly to electrical equipment that is used by being attached to a telephone pole that supports overhead wires for transmitting and distributing electricity to general consumers. It is something.

Generally, electrical equipment such as fuses and transformers required for delivery rooms are often attached to and supported on utility poles that support overhead wires for transporting power to consumers. The present invention relates to electrical equipment that is combined with utility poles in this manner.

[Prior art]

Traditionally, power was supplied to general consumers from the power company's distribution substation through muA kV high-voltage overhead lines as shown in Figure 1.
The high-voltage overhead line / is supported by an insulator attached to a utility pole, and the cut-out fuse 3. is also supported by the utility pole. Power was supplied through electrical equipment such as a transformer. For lightning surge protection, etc., i.e. to protect insulators and electrical equipment.

A lightning arrester 5 is also attached to the utility pole base. Each electrical device and insulator is supported by attaching it to a utility pole base made of concrete or wood via a support member 7 with bolts, etc. Wiring between devices was done outside the utility pole.

As described above, installing supports and electrical equipment on utility poles and wiring between each electrical equipment, overhead wires, etc. requires an extremely large amount of time and labor, and has the disadvantage of being expensive. Also, the wiring was exposed, which made it look different.

[Summary of the invention]

This invention was made in view of the above-mentioned drawbacks of conventional utility poles and electrical equipment, and provides an electrical equipment that is easy to install on N poles, requires less time and effort, and has a good appearance. A supporting terminal fitting that engages with the connecting terminal of the electrical equipment, a connecting conductor between the supporting terminal fittings, and a terminal fitting that connects the supporting terminal fitting and the overhead line, for the purpose of By simply engaging the connecting terminal and the support terminal fitting by combining the connecting conductor between them with a utility pole integrally cast or molded with an insulator,
Easy and easy VC! The electric device can be attached to a utility pole and supported, saving the trouble of wiring and providing a good-looking electrical device.

[Embodiments of the invention]

The present invention will be described in detail below with reference to an embodiment shown in the drawings.

As shown in Figures 2 and 3, high-voltage overhead lines 11 for power distribution
is connected to the terminal fitting /, 2 & C on the utility pole, but the terminal fitting /U is integrally cast on the utility pole lB cast with an insulating material that can be cast, such as epoxy, and is insulated from the insulating terminal that is insulated from each other. It has become. The terminal fitting 12 is the same as the conventional one.
and conductors connected to electrical equipment such as lightning arresters lAr.
Although it is connected with.

In this invention, the utility pole is also integrally cast with a support terminal fitting/ga for receiving and connecting the connecting conductor/7a and electrical equipment near the surface of the utility pole made of P binding material. Furthermore, Hughes/,? For example, although it is conventional to be connected to electrical equipment such as a transformer,
A connecting conductor/7b for connection and a support terminal fitting ttb connected to this connecting conductor to support the transformer Lda and supply power to the transformer are also integrally cast with an insulating material, embedded in the utility pole, and fixed. ing. Similarly, the connecting conductor /7c for wiring from the transformer to the terminal fitting θ on the low voltage side is cast on the utility pole together with the terminal fitting -〇, and the grounding conductor /? from the lightning arrester /k is cast on the utility pole.
d is also cast and embedded within the telephone pole.

Lightning arrester 13, fuse 13. All electrical equipment attached to the utility pole 16, such as the transformer/4', is electrically and mechanically engaged with the support terminal fittings cast into the pole and has a hanging terminal l? It is equipped with It is best to use a type that can be connected by inserting the connecting terminal/wafer into the supporting terminal fitting. For example, as shown in FIG.

Connection terminal/Spherical part at the tip/? If the support terminal fitting is formed like a two-split rod-shaped body (formed and has a hole lzad shaped to match the outer shape of the rod-shaped body), the connection terminal /9
Just insert it into the supporting terminal fitting.

Electrical equipment can be attached to and held on utility poles.

Therefore, in this invention, when installing power distribution equipment,
As mentioned above, it is easy to erect a utility pole with supporting terminal fittings and connecting conductors cast in insulating material, wire overhead lines to this, and attach each electrical device to the utility pole by engaging the connecting terminals and supporting terminal fittings. If that's all you need, the construction will be completed.

〔Effect of the invention〕

As described above, the electrical/equipment of the present invention is extremely easy to attach to a utility pole; all that is required is to engage the connection terminal and the support terminal fitting, and there is no need for wiring between the electrical equipment. , does not require much labor and time for construction. In addition, there is no need to provide a support for electrical equipment on the utility pole, and connection conductors between electrical equipment do not need to be wired outside the utility pole.
Wiring is not exposed, the appearance is good, and it also has a beautifying effect.
