Product Introduction:
Rupture discs for power systems are a type of non-reclosing, single-use overpressure relief device, mainly installed in transformers and gas-insulated switchgear (GIS). They are suitable for rupture disc devices in the air-cooled island systems of thermal power plants; special rupture disc safety devices for fully enclosed combined electrical switchgear GIS, high-voltage switchgear C-GIS, transformers, and lightning arresters; and rupture disc devices on equipment such as new energy vehicle lithium batteries and wind turbines.
Advantages of Rupture Disc for Power System:
1. Fast response.
The activation speed of this high pressure burst disc can reach the millisecond level, allowing it to rupture instantaneously to relieve pressure when internal device pressure rises. Tests have shown that under transformer fault conditions, the burst speed and relief efficiency of the rupture disc are higher than those of traditional pressure relief valves, effectively preventing equipment explosion accidents.
2. Controllable pressure.
By precisely machining specific-shaped grooves on the diaphragm, the burst pressure deviation can be controlled within ±5%. This design reduces the issue of debris splashing caused by pressure bursts.
3. Non-fragmenting.
With an arched structural design, the disc tears accurately along preset weak points during bursting, forming a regular opening without generating fragments. This is crucial for protecting downstream equipment and reducing pipe blockages or component damage.
4. Good sealing.
This pressure rupture disc can achieve zero-leakage sealing, suitable for equipment requiring a high degree of airtightness such as GIS and high-voltage switchgear. Additionally, using materials like stainless steel, Hastelloy, and duplex steel with anti-corrosion coatings allows long-term resistance to moisture, condensate, and corrosive media.
5. Long service life.
Rupture Discs for Electrical Equipment have a long working life and do not fail due to fatigue even under high-pressure conditions.
Applications of Rupture Disc for Power System.
1. Can be used in transformer systems.
This is one of the most typical application scenarios for rupture discs in power systems. When a high-voltage transformer experiences an internal fault, if the pressure cannot be released in time, it can easily cause the oil tank to deform or even rupture, potentially leading to explosive incidents.
2. Can be used in turbine systems.
Rupture discs used in power systems play an important role in overpressure protection for turbines, mainly helping to prevent mechanical damage caused by excessively high exhaust pressure. Specific applications include low-pressure cylinder explosion prevention and atmospheric valve applications.
3. Can be used in boiler and steam systems.
Most fossil fuel and nuclear power plants rely on generating pressurized steam to drive turbines and generators. Rupture discs used in power systems can help maintain safe operating pressure levels in boilers and the connected steam and condensate piping.
4. Can be used in switchgear.
Fully enclosed gas-insulated switchgear (GIS), high-voltage switchgear (C-GIS), transformers, surge arresters, and other equipment can be equipped with rupture Discs for Electrical Equipment for safety. These devices require high airtightness, and the zero-leakage sealing performance of high pressure burst disc is particularly crucial.
5. Can be used in fuel storage and delivery systems.
Suitable for storage tanks containing liquid petroleum, biofuels, natural gas, and propane, as well as coal bunkers with combustible dust. Pumps for liquid fuels, chemical feed pumps for regulating fuel and boiler water, and pumps for circulating cooling water rely on high-pressure burst discs to prevent excessive discharge-side pressure, relieve backpressure, and reduce the potential for damage to pumps, valves, and process instruments.
Relevant information to be noted in the power industry:
When using rupture discs in power systems, attention should be paid to selection, installation, maintenance, and safety management to ensure that they can reliably release pressure during overpressure, protecting equipment safety.
1. Selection: This includes pressure matching (the minimum burst pressure of rupture discs used in power systems should be 1.1 times higher than the normal operating pressure of the equipment), temperature adaptability (choose high-temperature resistant materials such as stainless steel or nickel-based alloys to ensure burst pressure stability at the design temperature), and medium compatibility (choose corrosion-resistant materials), among others.
2. Installation specifications: This includes orientation and position (easy for inspection and replacement, away from heat sources or vibration sources), pipeline connection (should be unobstructed, without sharp bends or blockages), sealing and fixation (to prevent local overpressure from causing rupture disc breakage), etc.
3. Maintenance and replacement: Regular inspections are required; pay attention to replacement cycles (2-3 years, 1-2 years in corrosive media or high temperature and high pressure conditions); safe operation (shutdown and depressurization must be performed during replacement); after replacement, recheck the installation orientation and sealing before putting it into operation.
These methods can effectively improve the safety of systems in the power industry and reduce various risks caused by overpressure. At the same time, enterprises should also strengthen safety education and training for employees to improve their knowledge of rupture disc usage.

FAQ.
1. How is the quality of rupture discs guaranteed?
Our rupture discs undergo a strict quality control process, including raw material inspection, production process monitoring, and comprehensive testing of the final product.
2. What are the benefits of using rupture discs in power systems?
Rupture discs for power systems are high pressure rupture disc that can achieve millisecond-level rapid pressure relief, effectively preventing explosions in transformers, GIS, and other equipment.
3. What precautions should be taken when using high pressure rupture disc in power systems?
It is forbidden to install any devices on the rupture disc that would restrict its operation, ensuring it can rupture freely under overpressure. If the rupture disc is used in series with a safety valve, the pressure indicating device between them must be checked regularly to prevent abnormal pressure in the intermediate chamber.
