Tilgu sequies3Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, it shall be handled properly.
There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.
burkina faso .Hand touch method for transformer inspection
Careless maintenance and insulation damage
.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing,burkina faso Parameters of 1250kva oil immersed transformer, while oil transformers mostly use porcelain waterproof casing;
The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.
The raw materials of Fushi blue can be used for bonding,burkina faso Substation transformer, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
Oil leakage of bolt or pipe external thread
Maintenance contents of power transformer
The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.

Oil leakage at looper flange
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing while oil transformers mostly use porcelain waterproof casing;
High voltage fuse of transformer breaks one phase;
Inspection environment.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer,burkina faso S11 dry type transformer manufacturer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.
(5) the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.
burkina faso .In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So
