Santa Rosa LimFault judgment of power transformer
Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.
Santa Ana.The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, offset, cracking, loosening ignition smoke, oil leakage, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity, which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.
Sound in case of phase failure
.Power transformer
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.
(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation,Santa AnaStandard for operating temperature of oil immersed transformer, a spacing of more than 2m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a guardrail of no less than 7m shall be installed around it, and a warning sign shall be hung at a prominent position.
Two point grounding device of iron core caused by residual welding scar;
During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.
Quality improvement.When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
The noise of dry-type transformer comes from
Power transformer manufacturer
Before no-load impulse closing, the transformer shall be placed for 24h,Santa AnaComputer temperature controller for dry-type transformer, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
Welcome calls .Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod,Santa AnaDry type transformer ranking, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, please connect all routes as far as possible to prevent other faults.
How to select dry-type transformer
The hanging core of dry-type transformer is a vital part
Santa Ana.Analysis of common faults of oil immersed transformer:
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, what is the wiring mode of dry-type transformer?
Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, airports tunnel construction, chemical enterprises and factories.
