The raw materials of Fushi blue can be used for bonding， 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.
When the full load test is carried out and everything is normal， the load can be connected.
JhingergachaHow to select dry-type transformer
The bearing capacity of each load is different. Generally， dry-type transformer should operate under rated capacity，Jhingergacha800 oil immersed transformer， while oil transformer has better load working capacity.

For example， in the s， and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer， and then lead a point of it out of the road with transmission line， which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances， office and other electrical equipment.
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil， resulting in short circuit between coils， two-color short circuit or short circuit on the ground， resulting in the ignition of power transformer. Therefore， the insulation compressive strength of power transformer shall be tested before installation and operation， and overload is not allowed in the whole process of operation.
Wiring mode of dry-type transformer:
Transformer is
A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
reformDuring 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.
For kVA power engineering transformer， plastic parts are selected in the middle of iron core， clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.

Potential developmentDuring 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.
Step up process of dry-type transformer?
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings， because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding， most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding， that is， the disconnection component of the electric field is small.
Jhingergacha& ldquo; YN， D & rdquo;， in which indicates that when the working voltage phasor of the primary side line，JhingergachaWind power box transformer， refers to the position at o"clock， the phase voltage phasor of the secondary side is at o"clock. That is the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).
Note: in the whole process of safety patrol inspection，JhingergachaHandover test contents of dry-type transformer， terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal， significantly expanded， or there is local sound the cause shall be found immediately and certain effective measures shall be taken. If necessary， the load can be reduced or the operation of the transformer can be stopped.
In order to better carry out the experiment of power transformer oil， it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than .kg， and the oil sample for simplified experiment shall not be less than kg.
