Description

Environment-friendly inflatable cabinet air chamber device

Technical Field

The invention mainly relates to the technical field of power equipment, in particular to an environment-friendly air chamber device of an inflatable cabinet.

Background

In China, SF6 gas insulated switchgear is widely adopted in the national power system at present, however, sulfur hexafluoride is a strong greenhouse gas, and the Global Warming Potential (GWP) of the sulfur hexafluoride is as high as 23500. Therefore, the search for an environmentally friendly gas that can partially or completely replace SF6 is an urgent need for the development of the power industry.

The popularization and application of SF 6-free distribution switchgear are increased by national grid companies, and SF 6-free switchgear such as vacuum arc extinguishing, dry air or N2 insulation and the like is popularized in the field of 10-35KV power grids. By adopting the principle of pilot-time advance and gradual popularization, the application proportion of the SF 6-free switch equipment is enlarged year by year, and the full coverage of the newly-added SF 6-free switch equipment is realized by 2023.

The dry air insulation switch equipment meets the application requirements of the future market, the product takes dry air as an insulation medium (the dry air is an industrial mixed gas, 19.5-23.5% of the dry air is oxygen, and the rest is nitrogen), no pollutant is discharged in the production link, no waste gas is discharged in the use process of the equipment and after the equipment is in service life, and excellent environmental protection performance is highlighted. However, in the insulation effect evaluation of the dry air insulation switchgear, compared with SF6, the performance of dry air insulation is obviously lower than that of SF6.SF6 gas has excellent arc extinguishing and insulating properties, is stable and nontoxic in chemical properties, is insulating gas with the widest application and the best service performance in the current power equipment, and needs to solve a series of technical difficulties if dry air is used for insulation:

1. ensuring insulating ability

Compared with the excellent arc extinguishing and insulating performance of SF6, the dry air arc extinguishing and insulating performance is poor. Therefore, it is necessary to make a rational design in terms of product design layout, part shape, and part size, otherwise it is difficult to meet the related art requirements.

2. Temperature rise and heat dissipation

The gas insulated metal enclosed switchgear seals the high voltage part in a stainless steel gas box and uses a small amount of solid insulating material, such as epoxy, silica gel, etc., to increase the insulating strength, especially N2 or dry air, whose temperature rise margin is more than 10K greater than SF6. Therefore, how to effectively control the temperature and solve the heat dissipation problem of the compact gas-insulated metal-sealed switchgear becomes a difficult problem of the research thereof.

3. Product miniaturization and production cost control

In the gas insulated metal-enclosed switchgear, if an environment-friendly gas is used, the breaking performance thereof is lowered, and a vacuum arc-extinguishing chamber is required to improve the breaking performance thereof, so that the volume of the product is increased, and the production cost is also increased. How to miniaturize products and control production costs is one of the research points.

4. Product structural strength and reliable safety

The electric power equipment has good safety and reliability, a reasonable structure is designed, the equipment is ensured to operate stably, the product strength is ensured to be sufficient under the abnormal condition, and the research focus is on not endangering the personal safety.

As described above, compared with the safety of the insulating medium, the environment-friendly gas medium mainly containing dry air and nitrogen is relatively a solid insulating material and SF ₆ Gas, which has the performance advantages of self-healing function, no generation of toxic gases, and no adverse effects on the environment and personal safety. When the gas insulation switch cabinet is adopted, the environment-friendly gas is preferably selected and selected as an insulation medium, so that the safety, the reliability and the environment-friendly performance of the power grid equipment are protected.

Currently, in the field of 10-35KV medium-high voltage power grids, the current-class environment-friendly gas-insulated metal-enclosed switchgear (CGIS) of 1250A or above is widely used in countries in europe and america, the technology is relatively mature, only a few enterprises in China develop and produce, and the CGIS is still in the initial stage of industry research, development and application. The technical scheme is mainly from foreign well-known enterprises such as ABB, siemens, schneider and the like. The product technology in Europe and America is relatively mature, and the reliability and the safety basically meet the requirements, but the problems of complex equipment structure, overhigh product cost and the like exist, and the large-range application cannot be realized.

The domestic manufacturers respectively use different design experiences of foreign enterprises for reference and make design improvement according to the domestic practical application condition. The core of the CGIS-12 (Z) type 12kv environment-friendly gas-insulated metal-enclosed switchgear is a gas chamber, and the inside of the gas chamber comprises main product core components: the device comprises a three-station mechanism, a vacuum circuit breaker, a connecting copper bar, an insulating part and the like. At present, all manufacturers are different in design structure and product component selection, and have no unified standard scheme, which is mainly expressed as follows:

1. the internal elements are arranged differently;

2. the shape, size, structure and manufacturing process of the air chamber are different;

3. the main core elements are different in type selection;

4. the pressure relief device has different positions, heat dissipation modes and the like.

Therefore, the technical routes at home and abroad are different at present and have advantages and disadvantages respectively.

The defects of the domestic and foreign technology in the design of the gas chamber structure of the CGIS-12 (Z)/T1250-31.5 type environment-friendly gas-insulated metal-enclosed switchgear are as follows:

1. part of manufacturers of the pressure relief devices are arranged at the upper part or the side part of the air chamber, have no independent pressure relief channel, do not accord with the standard requirements of the power grid equipment in China, and are difficult to obtain the approval of domestic customers;

2. the strength of the designed structure of the air chamber is not enough, and potential safety hazards exist when equipment is abnormal;

3. in order to ensure the insulating property and reduce the temperature rise, part of manufacturers adopt double copper bars for connection, so that the installation is inconvenient and the material cost is overhigh;

4. the arrangement of the internal elements of the air chamber is unreasonable, and the installation and the maintenance are inconvenient.
