Product description

Before installing the S11-400KVA/10KV/0.4KV oil-immersed transformer, it is necessary to carry out the safety construction of a small natural environment, that is to say, according to the power switch, the power supply circuit in the area is temporarily turned off first, and an unplugged safe natural environment is set up for the actual operation staff before the installation can be carried out.

S11-400KVA/10KV/0.4KV oil-immersed transformer manufacturers in addition, in the whole process of installation, should pay attention to the specific application of S11-400KVA/10KV/0.4KV oil-immersed transformer 1 attention and flexible changes, such as dry-type transformer independent application and group chat application, their routes are all over that is to say, different, everyone should be installed at the time of installation according to the specific situation to hang the wire.

Secondly, after the installation is done, it can not be plugged in immediately, but it should be used to carry out a test with a reserved small switching power supply, and use a capacitive pen to test the input and output working voltage of the S11-400KVA/10KV/0.4KV oil-immersed transformer.

Reasonable layout features:

1. The high and high pressure winding resistance is all made of copper foil (foil);

2. The high and high pressure winding resistance is all poured with epoxy resin in the vacuum pump and dried to form a reasonable layout of high-toughness FRP;

3. The high and high voltage winding resistance is set up with vertical ventilation air duct in accordance with the heat pipe heat dissipation regulations;

4. The inner and surface layers of the electromagnetic coil are lifted by glass fiber alkali-resistant mesh cloth;

5. The insulation layer grade has F and H grades;

6. S11-400KVA/10KV/0.4KV oil-immersed transformer is light and light. The S11-400KVA/10KV/0.4KV oil-immersed transformer can be installed with a temperature presentation controller to display and control the operating temperature of the transformer winding, and the service life of the maintenance port transformer is usually used. The temperature sensor PT100 platinum resistance is inserted into the high voltage winding resistance to obtain the temperature signal signal, and after the power supply circuit is processed, the wheel on the control board presents the temperature of each phase winding resistance. It has the function of temperature setting, manual/active start-stop centrifugal fan, retrieval problem, overheating light control flag signal alarm and overheating active power trip, etc., and has the anti-electromagnetic nuisance ability required by the family. In addition, there is an intelligent machine socket embedded to maintain long-distance control. S11-400KVA/10KV/0.4KV oil-immersed transformer is equipped with a low-amplitude flow fan, which can reduce the winding temperature after starting, develop the load capacity, and broaden the service life of the transformer; When using forced air cooling, the short-circuit capacity can be developed by 40-50%.
