Abstract
A depressurization system for an electrical transformer includes a pressure release assembly configured to be in fluid communication with a chamber of the electrical transformer. The pressure release assembly includes a rupture pin valve. The system may include an evacuation assembly having a blast chamber. The rupture pin valve includes a pin configured to buckle in response to a predetermined pressure applied to a surface of the rupture pin valve.
Claims20
A depressurization system for an electrical transformer comprising:
- a pressure release assembly configured to be in fluid communication with a chamber of an electrical transformer;
- wherein the pressure release assembly comprises a rupture pin valve.
A depressurization system for an electrical transformer comprising:
- a pressure release mechanism to provide selective fluid communication with a sealed chamber of an electrical transformer;
- and
- an evacuation assembly coupled to the pressure release mechanism;
- wherein the evacuation assembly comprises a blast chamber that is disposed in close proximity to the pressure release mechanism, wherein the blast chamber is configured to reduce a flow restriction within the depressurization system.
A method of depressurizing a chamber of an electrical transformer comprising:
- pressurizing a surface of a rupture pin valve with fluid from a chamber of an electrical transformer;
- and
- actuating the rupture pin valve in response to the pressurization of the surface of the rupture pin valve.
The method of 15, further comprising directing a fluid from the transformer chamber to a blast chamber via the actuated rupture pin valve, wherein the blast chamber is in close proximity to the rupture pin valve, and expanding the fluid in the blast chamber.
