Description

An insulating support member for installation of a street lamp ballast

technical field

The invention relates to an insulating supporting piece for ballast installation, in particular to an insulating supporting piece for installing a ballast specially used for street lamps.

Background technique

At present, in my country's urban street lighting system, there is a high-pressure sodium lamp ballast. Due to its heavy weight, an iron shell is used to increase its strength during manufacture. The street lamp poles for urban street lighting basically use beautiful metal lamp poles. Installed on the metal light pole, if the ballast fails, the shell will be charged and transmitted to the entire metal light pole. If a pedestrian holds the live metal light pole, there will be a risk of electric shock.

There are two installation techniques at present: the first technique is to coat the rectifier shell with insulating varnish; the second technique is to pad the entire bottom of the rectifier with an insulating plate before installation.

The problem with the first process is that the insulating layer is easily damaged when the bolts are fixed during the installation process, and the insulating paint is easy to age and fall off over time, resulting in leakage; the second process makes up for the first one to a certain extent. Defects, but the space in the street light pole is small, the installation is more troublesome, and the cost of the whole insulation board is very high, there are certain hidden dangers when the bolts pass through the U-shaped mounting holes of the ballast, and there may be contact between the bolts and the U-shaped holes, Cause live ballast to pass through the bolt to the metal light pole.

In view of this, the inventor conducted research on this, and specially developed an insulating support for installing street lamp ballasts, and this case arose from this.

Contents of the invention

The purpose of the present invention is to provide an insulating support for street lamp ballast installation. When installing the ballast, an insulating support is put on to completely isolate the ballast body from the metal light pole, and the support passes through the U-shaped installation hole. , The mounting bolts pass through the support, so that the bolts and the U-shaped mounting holes are completely isolated, and the problem of the metal lamp pole being charged due to the ballast failure is eliminated.

In order to achieve the above object, the solution of the present invention is:

An insulating support for installing a street lamp ballast, comprising a main body of the support, and an upper gasket and a lower gasket connected to both ends of the main body of the support, wherein the upper gasket, the lower gasket and the main body of the support form a mounting groove; the The main body of the support is a cylindrical structure with through holes passing through both ends.

As a preference, the upper gasket and the lower gasket are screwed to both ends of the main body of the support, the outer walls of the two ends of the main body of the support are provided with external threads connecting the upper gasket and the lower gasket, and the upper gasket and the lower gasket are provided with There are internal threads that match the external threads.

Preferably, the main body of the support, the upper pad and the lower pad are integrally structured.

Preferably, the through hole of the main body of the support is circular or hexagonal, which is used for the smooth passing of the mounting bolts.

Preferably, the main body of the support has a wall thickness of 5-10 mm, a through hole diameter of 8-15 mm, and a length of 10-20 mm. The main body of the support has a certain wall thickness to ensure strength and insulation effect.

Preferably, the upper gasket and the lower gasket have the same structural size, the outer diameter is 40-80mm, and the thickness is 3-8mm. drop.

Preferably, the width of the installation groove is 4-8 mm. The installation groove just fits in the buckle of the U-shaped installation hole of the ballast.

Preferably, the main body of the support, the upper pad and the lower pad are made of engineering plastics.

The street lamp ballast installation insulation supporting part of the present invention has the characteristics of simple structure, small size, light weight, high strength, strong aging resistance, simple installation, convenient disassembly and assembly, and low price. This kind of street lamp ballast is installed with insulating support parts, which can completely solve the current problem of live transmission of faulty ballasts to metal light poles, and solve the risk of electric shock caused by pedestrians holding metal light poles from the source of leakage power.

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

detailed description

Example 1

An insulating support for installing a street lamp ballast, comprising a support main body 1, an upper gasket 2 and a lower gasket 3 screwed to both ends of the support main body 1, the upper gasket 2, the lower gasket 3 and the support main body 1 forms an installation groove 4; the main body 1 of the support member, the upper gasket 2 and the lower gasket 3 are all made of reinforced engineering plastics. The main body 1 of the support member is a cylindrical structure, and there are through holes 11 penetrating both ends inside, and the through holes 11 may be circular or hexagonal. The outer walls at both ends of the support body 1 are provided with external threads 12 connecting the upper gasket 2 and the lower gasket 3, and the upper gasket 2 and the lower gasket 3 are provided with internal threads 21, 31 that match the external threads 12. .
