Description

High-voltage isolating switch base

Technical Field

The utility model relates to a high voltage isolator base field especially relates to a high voltage isolator base.

Background

The high-voltage isolating switch is an important switching device in an electric system of a power plant and a transformer substation and needs to be matched with a high-voltage circuit breaker for use. The isolating switch is suitable for indoor devices with three-phase alternating current of 50Hz and rated voltage of 12 KV. For switching on, switching off or switching over the line in the event of a voltage-loaded train load of the high-voltage installation. The main functions are as follows: the safety of the high-voltage electrical appliance and the device during maintenance work is ensured, the voltage isolation function is realized, the high-voltage electrical appliance and the device cannot be used for cutting off, inputting load current and cutting off short-circuit current, and only can be used for certain switching operation without generating strong electric arcs, namely the high-voltage electrical appliance and the device do not have the arc extinguishing function; the device is divided into an indoor type and an outdoor type according to different installation places, and is divided into a single-column type, a double-column type and a three-column type according to the number of the insulating support columns, and optional equipment is arranged at each voltage class.

The commonly used high-voltage isolating switch ZW39-40.5 base is easy to deform during casting and heat treatment, the shaping difficulty is high, the production yield is low, and the cost is high, so that a high-voltage isolating switch base is needed to be provided to solve the technical problems.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, a high-voltage isolator base is provided.

The utility model provides a technical scheme that its technical problem adopted is: the high-voltage isolating switch base comprises a base body and further comprises a bearing hole, first reinforcing ribs, second reinforcing ribs and a label area, wherein the surface of the base body is provided with a plurality of groups of bearing holes, each group of bearing holes are provided with a plurality of groups of first reinforcing ribs, the surface of the base body is provided with the second reinforcing ribs, and the end on the surface of the base body is provided with the label area.

The utility model provides a pair of in high voltage isolator base, the dead eye runs through the front and the back of base body, and the dead eye at the base body front and the back all is provided with the first strengthening rib of multiunit all around.

The utility model provides a pair of in high voltage isolator base, the front and the back of base body all are provided with the second strengthening rib.

Compared with the prior art, the utility model provides a pair of high voltage isolator base has following beneficial effect:

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Exemplary embodiments of the present invention are shown in the drawings.

The first embodiment is as follows:

as shown in fig. 1, the utility model discloses a high-voltage isolation switch base, including base body 1, still include dead eye 2, first strengthening rib 3, second strengthening rib 4 and label area 5, base body 1's surface is provided with multiunit dead eye 2, the surface of every dead eye 2 of group all is provided with the first strengthening rib 3 of multiunit, base body 1's surface is provided with second strengthening rib 4, the end on base body 1 surface is provided with label area 5, through improving base body 1's structure commonly used, utilize the intensity of first strengthening rib 3 greatly increased dead eye 2 department, simultaneously through the setting of second strengthening rib 4, the deflection of base body 1 when casting and thermal treatment can effectively be reduced, thereby greatly improve the production volume, the cost is reduced, the practicality is higher, wide development space and higher spreading value have.

As shown in fig. 1 to 6, the bearing holes 2 penetrate through the front and back of the base body 1, a plurality of groups of first reinforcing ribs 3 are disposed around the bearing holes 2 on the front and back of the base body 1, and second reinforcing ribs 4 are disposed on the front and back of the base body 1.

The utility model provides a pair of high voltage isolator base's theory of operation as follows:

through improving the structure of base body 1 commonly used, utilize first strengthening rib 3 greatly increased the intensity of 2 departments of dead eye, simultaneously through the setting of second strengthening rib 4, can effectively reduce the deflection of base body 1 when casting and thermal treatment, solved high-pressure isolator ZW39-40.5 base commonly used, yielding when casting and thermal treatment, the plastic degree of difficulty is great, leads to the production output to be low, problem with higher costs.
