Product Description
Main application
Buchholz relay type QJ is a kind of protective device used for oil immersed transformer with conservator and on-load tap changer. If a fault generated inside the transformer(or the on-load tap changer), cause gases generated from oil decomposed. When the amount of gas accumulate up to a stated level, the signal contact of buchholz relay turns on and send alarm signal. When a serious fault generates inside transformer or on-load tap changer, the transformer oil surge will happen, oil flow heavily in the pipeline and result in the operation of baffle plate of buchholz relay leads to the trip contact turning on, so trips the transformer. If the oil level is low due to the oil losses, the alarms is also initiated.
| assembling method | the relay's pipe axis should be parallel to the transformer case cover,and it is allowed for the end leading to the conservator is highter,however the inclination between the axis and level surface may not exceed 4% |
| structure of the gas relay | the relay's core structure is shown in fig.1 and the relay's upper core consist of gas lock1,gas lock nut 2,probe 3,blocking 4,snap ring(float) 5,weight drop6,guard board 7,magnet 8, connecting terminal 9,spring 10,regulating rod11 and dry reed contact12.formin a flow device that acts on tripping,gas lock 1 in the cover is used for exhaustion in the case of assembly and extracting gas out of order. probe 3 is used to check flexibility and reliability of the tripping mechanism. |
