Abstract
This utility model relates to a kind of gases at high pressure switchgear with low-temperature protection device; including chopper one pole; chopper one pole includes the arc-chutes being sequentially connected with, single-phase pillar and transmission crank arm box, and the attachment means of single-phase pillar and transmission crank arm box is provided with low-temperature protection device.This utility model by switchgear the single-phase pillar of chopper with low-temperature protection device is set between transmission crank arm box and is connected trachea outer wrapping heat-insulating heat-preserving material at interpolar; guarantee that when SF6 gas circulates, the temperature difference is unsuitable excessive; under the conditions of not changing conventional products structure and operational factor, make substation equipment also can run safely and reliably under rigor condition.
Description
Technical field
This utility model relates to technical field of electric equipment, particularly relates to one and has low-temperature protection
The gases at high pressure switchgear of device.
Background technology
Outdoor high voltage switchgear is often as arc extinguishing and dielectric with SF6 gas, has
Cut-off that capacity is big, dielectric level advantages of higher, extensively apply at high pressure and supertension field.If
When the chopper of one of standby middle Primary Component runs, three pole gases are interconnected, and use pointer-type close
Its gas pressure is protected and monitors by degree relay.According to the characteristic of SF6 gas, SF6
Being filled with under rated pressure 0.6MPa under room temperature (20 DEG C) state has well insulation and cut-offs
Performance；But when equal pressure environment temperature is below-30 DEG C, SF6 gas will liquefy
Phenomenon, greatly reduces the safe handling of switchgear and chopper, has a strong impact on product and runs
Safety and reliability.Especially the lowest in east the Northwest of China and outlet Russia etc.
Temperature area (temperature as little as-40～-60 DEG C), conventional products will be unable to meet and uses requirement.
Utility model content
This utility model aims to provide a kind of gases at high pressure switch with low-temperature protection device and sets
Standby, it can be ensured that under low temperature state, SF6 gas is not liquefied.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
A kind of gases at high pressure switchgear with low-temperature protection device, including chopper one pole,
Described chopper one pole includes the arc-chutes being sequentially connected with, single-phase pillar and transmission crank arm box, institute
The attachment means stating single-phase pillar and transmission crank arm box is provided with low-temperature protection device.
Preferably, described chopper one pole has 3, and 3 chopper one poles are arranged on base,
Base is provided with the interpolar connection trachea connecting 3 chopper one poles, described connection trachea outer wall bag
It is wrapped with heat-insulating heat-preserving material.
Preferably, described low-temperature protection device is heating tape, and described heating tape is around attachment means
Peripheral one week.
Further, 3 chopper one poles at equal intervals, be arranged in parallel.
Preferably, described base is provided with the heater A to heat-insulating heat-preserving material heating.
Further, described low-temperature protection device is connected with the heater B in mechanism case, described
Heater B is controlled by the temperature controller in mechanism case.
Further, described heater A is provided with 3 at equal intervals.
Compared with prior art, this utility model has the advantages that
Protect by arranging low temperature between the single-phase pillar of the chopper of switchgear and transmission crank arm box
Protection unit and interpolar connect trachea outer wrapping heat-insulating heat-preserving material, it is ensured that SF6 gas stream
Time logical, the temperature difference is unsuitable excessive, under the conditions of not changing conventional products structure and operational factor, makes change
Power station equipment also can run under rigor condition safely and reliably.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing in Fig. 1 at A；
Fig. 3 is the structural representation of chopper one pole；
Fig. 4 is the structural representation of base；
In figure: 1-chopper one pole, 2-low-temperature protection device, 3-arc-chutes, the single-phase pillar of 4-,
5-transmission crank arm box, 6-interpolar connect trachea, 7-mechanism case, 8-base, 9-heater A.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below
In conjunction with accompanying drawing, this utility model is further elaborated.
As it is shown in figure 1, the gases at high pressure disclosed in this utility model with low-temperature protection device are opened
Pass equipment, including chopper one pole 1, arc-chutes 3 that chopper one pole 1 includes being sequentially connected with,
Single-phase pillar 4 and transmission crank arm box 5, single-phase pillar 4 and the attachment means of transmission crank arm box 5
It is provided with low-temperature protection device 2, low-temperature protection device 2 and the heater B phase in mechanism case 7
Even, described heater B is controlled by the temperature controller in mechanism case 7.Low-temperature protection device 2 is preferred
For heating tape, heating tape was around peripheral one week of attachment means.When ambient temperature is pre-less than temperature controller
During first setting value, heater B will devote oneself to work, it is ensured that the SF6 gas in each air chamber not by
Liquefaction, after temperature rises to certain value, heater B will quit work.
Chopper one pole 1 has 3,3 chopper one poles 1 at equal intervals, be installed in parallel in the end
On seat 8, three chopper one poles 1 form three grades of choppers, and base 8 is provided with connection 3
The interpolar of individual chopper one pole 1 connects trachea 6, connects trachea 6 outer wall and is enclosed with heat-insulation and heat-preservation
Material, base 8 is provided with heater A9, heater A9 and is provided with 3 at equal intervals.
Certainly, this utility model also can have other numerous embodiments, new without departing substantially from this practicality
In the case of type spirit and essence thereof, those of ordinary skill in the art can be according to this utility model
Make various corresponding change and deformation, but these change accordingly and deformation all should belong to this reality
By novel appended scope of the claims.
