Abstract
The present invention discloses an isolation protection method of a distribution transformer tap changer. According to the method, the distribution transformer tap changer is closed, and the damage of the dielectric strength of insulating oil caused by mixing the metal debris and other micro particles into the insulating oil is effectively prevented. The invention also discloses an isolation protection device of a distribution transformer tap changer, and particularly relates to a closed shell device with a special material and a special shape. The closed shell device is the device employed by the isolation protection method of a distribution transformer tap changer, and the closing of the distribution transformer tap changer can be realized without changing the structure of the tap changer.
Description
Art
The invention discloses a kind of isolating and protecting method of distribution transformer tap changer and device, belong to power system power transformation, distribution technique field.
Background technology
The microparticles such as the tap changer of regular distribution transformator is exposed in fuel tank, the metal fragment in tap changer operating process are directly mixed with in insulating oil, and insulating oil dielectric strength is damaged.These microparticles also can with in the insulation system flowing into winding of insulating oil, and after causing longtime running, insulating capacity declines, and causes a hidden trouble to safe operation.
Goal of the invention and content
The invention discloses a kind of isolating and protecting method of distribution transformer tap changer, the method, by airtight for distribution transformer tap changer, be prevented effectively from the microparticles such as metal fragment and be directly mixed with in insulating oil, insulating oil dielectric strength is damaged.
The invention also discloses the isolation protecting device of a kind of distribution transformer tap changer, it is specifically related to the closed shell device of a kind of special substance, special shape, this closed shell device is the device that the isolating and protecting method of distribution transformer tap changer adopts, the structure of tap changer can not be changed, it is achieved distribution transformer tap changer airtight.
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Accompanying drawing explanation
Accompanying drawing is axonometric chart of the present invention.Wherein: 1 shunting switch, paper shell on 2,3 connect paperboard strip, 4 times paper shells.
In conjunction with accompanying drawing, the invention will be further described.These accompanying drawings are the schematic diagram of simplification, and the basic skills of the present invention is only described in a schematic way, the composition that therefore only display is relevant with the present invention.
The invention discloses a kind of isolating and protecting method of distribution transformer tap changer and device, it is accomplished by
With electrician's cardboard with good mechanical strength, higher electric strength, the profile according to distribution transformer tap changer, the closed shell made of white glue with vinyl bonding；In distribution transformer tap changer is completely encapsulated in by shell.
Cover top portion leaves oil circulation hole, and, according to distribution transformer tap changer contact position perforate, there is the latter half total enclosing at middle part, for the deposition of microparticle.
