Which items should be checked before the voltage transformer is put into operation?
    Before the voltage transformer is put into operation, it shall be tested and qualified according to the handover test items of the relevant regulations. The specific inspection items are as follows: (1) The appearance of the oil-filled transformer should be clean, the oil level is correct, and there is no leakage.     (2) Porcelain bushings or other insulating media are free of cracks.     (3) The primary side lead and the secondary side circuit are screwed tightly and the contact is good.     (4) The outer casing and the secondary circuit should be grounded at one point.
(1) Large screen
temperature indication with heating indicator light, working status at a
glance.
(2) Microcomputer
control, heating and insulation automatic control.
(3) The inner
liner is made of high-quality steel plate and equipped with a liner protection
device, which is anti-corrosion and pressure-resistant and durable.
(4) It has
multiple safety protection functions such as leakage protection, anti-dry
protection, over-temperature protection, over-pressure protection, and leakage
warning.
(5) The insulation
layer is foamed with thickened polyurethane, which has good heat preservation
effect and saves energy.
(6) It has a wide
range of water pressure and large capacity, and can be used for water at the
same time.
