Description

A 10kV isolating switch mounting bracket

technical field

The utility model relates to the field of electric equipment, in particular to a mounting bracket for a 10kV isolating switch.

Background technique

The installation methods of the existing 10kV pole-mounted transformer isolating switch: inverted installation and vertical installation, the following problems exist during the operation or use of the switch:

(1) Wire hanging upside down: During the operation of the isolation switch, the insulating porcelain bottle is cracked or broken due to various factors. Sometimes the connecting wire falls with the broken porcelain bottle, hangs upside down on the main line, and shakes with the wind, which is easy to cause accidents.

(2) Accidental injury to electricians: In the upside-down mode of the isolating switch, the personnel must operate under the switch. Sometimes the porcelain bottle is cracked due to some factors but it does not crack. When the knife is pulled, the cracked porcelain body just falls on the operator. Body, easy to cause injury, there is a safety risk.

(3) Looseness of the knife switch: In the upside-down mode of the isolating switch, after a long period of operation, the clamping device of the knife switch is easy to loosen, and it is easy to leave the closing position, resulting in poor contact, heat generation, and even the knife switch opens by itself, resulting in non-human accidents.

(4) Inconvenient operation: when the isolating switch is installed vertically, sometimes the knife switch is not easy to close in place due to the angle problem during operation, which may cause poor contact and heat generation; under the above two methods, the operation of the sideline knife switch is prone to vibration.

(5) The cross arm is not universal: At present, there are two ways for the single-pole high-voltage downconductor in the station area: two lines run on the left or right.

Utility model content

The technical problem to be solved by the utility model is to provide a 10kV isolating switch mounting bracket, the isolating switch is installed at an angle of 45° relative to the vertical, the three-dimensional structure, the strength is stable, there is no need to distinguish the left or right cross arm, and the incoming and outgoing wires are fixed. Point, suitable for single pole high voltage down conductor.

In order to achieve the above purpose, the utility model provides the following technical solutions: a 10kV isolating switch mounting bracket, characterized in that: the 10kV isolating switch mounting bracket includes two base bracket angle steels with an "L" shape in section, the base bracket A number of installation holes are provided on both sides of the frame angle steel. A vertical connection angle steel is fixed between the two foundation bracket angle steels. One of the foundation bracket angle steels is fixed with a horizontal connection angle steel perpendicular to the vertical connection angle steel. The length of the horizontal connection angle steel and the vertical connection angle steel is equal. The other end of the horizontal connection angle steel is fixed with an "L"-shaped mounting plate bracket angle steel. There are several mounting holes on both sides of the mounting plate bracket angle steel. A disconnector switch is fixed between the mounting plate bracket angle steel and the foundation bracket angle steel. There are several mounting holes on the isolating switch mounting plate, and the isolating switch mounting plate forms an included angle of 45° with the horizontal connecting angle steel and the vertical connecting angle steel.

Preferably, the base bracket angle steel, the horizontal connection angle steel, the vertical connection angle steel, the isolation switch mounting plate, and the mounting plate bracket angle steel are all made of structural steel, and the surface is coated with a layer of zinc.

Preferably, the base bracket angle steel, the horizontal connection angle steel, the vertical connection angle steel, the isolation switch mounting plate, and the mounting plate bracket angle steel are all connected by welding.

The beneficial effect of adopting above technical scheme is:

(1) Prevent the wires from hanging upside down: install a needle-type porcelain bottle at the inlet and outlet ports of the isolation switch, and bind and fix the wires, which can prevent the connecting wires from hanging upside down on the main line with the broken switch porcelain bottle;

(2) Avoid accidentally injuring electricians: The isolating switch is installed with an inclination of 45°. Personnel do not operate under the switch, and there is a horizontal distance of more than 2m away from it. When pulling the knife switch, even if the cracked porcelain body falls down, it will not be rolled. on the operator, thereby avoiding injury;

(3) It is not easy for the knife to loosen: in the installation mode inclined at 45°, even if the clamping device of the knife is loosened after a long period of operation, it is not easy to leave the closing position due to the angle factor, reducing the occurrence of non-human accidents;

(4) Easy to operate and in place: in the installation mode inclined at 45°, it is easy to find the position facing the switch during operation. The insulating rod and the switch knife are at an angle between 75° and 90°, and can be easily put in place with appropriate force ;In addition, the improved mounting bracket adopts a three-dimensional structure, which is more stable and will not shake when operating the sideline knife switch;

(5) Universal cross arm: The single-rod high-voltage downconductor in the station area can use the improved bracket regardless of whether the two lines run on the left or the right. There is only one specification, and there will be no problem of mismatching the cross arm during installation.
