100KVA dry-type transformer is a new generation of energy-saving power transformer developed and produced by our factory on the basis of referring to similar international products and combining with China’s national conditions, from 300VA to 1600KVA, in line with national standards, and the winding adopts the whole winding method; The transformer is vacuum-impregnated, so that the insulation grade of the transformer reaches F or H, and the product performance reaches the standard level at home and abroad. 100KVA dry-type transformers are widely used in circuits with AC 50Hz to 60Hz and voltages below 660V, and are widely used in important equipment, precision machine tools, mechanical and electronic equipment, and medical treatment equipment, rectifiers, lighting, etc. The level of various input and output voltages of the product, the connection group, the number and position of the adjustment tap (generally ±5%), the distribution of winding capacity, the configuration of secondary single-phase winding, and rectification The use of circuits, whether it is required to have a shell, etc., can be carefully designed and manufactured according to the requirements of users.

Product Introduction

The 100KVA dry-type transformer is safe, flame retardant, fireproof, pollution-free, and can be installed directly in the load center. Maintenance-free and easy to install. It has good moisture-proof performance and can be put into operation without pre-drying after being out of operation. Low loss, low partial discharge, low noise, forced air cooling, 120% rated load operation. It has a complete temperature protection control system to provide reliable guarantee for the safe operation of the transformer. The reliability index of the product has reached the domestic advanced level.

100KVA dry-type transformer features:

1. The coil is wound with copper wire or foil, reinforced with glass fiber, epoxy resin is poured without filler, vacuum drying, degassing and dehumidification, high mechanical strength, short circuit resistance, and strong impact resistance.

2. The head end of the high-voltage winding and the middle tap tap are embedded with copper inserts, which has good rigidity, easy to adjust gears, and is beautiful and neat.

3. The iron core is made of high-quality grain-oriented cold-rolled silicon steel sheets, and the 45-degree full-oblique multi-step joints are stacked. The surface is covered with resin insulating coating, which is moisture-resistant, rust-proof, and noise-resistant.

4. The elastic parts are clamped between the core, the clamp and the coil to make the coil in a stable compression state to reduce noise.

5. The transformer is designed according to self-cooling, and a longitudinal ventilation channel is reserved inside the cylinder wall of the high-voltage (low-voltage) coil for overall casting, which can be equipped with a forced air cooling device (cooling fan), and the output capacity can be increased by 50% after the forced air cooling device is adopted.

6. Equipped with a thermostat, a platinum resistor (Pt100) is placed in the embedded hole at the top of the low-voltage coil. In order to monitor the temperature rise of the transformer winding, the cooling fan is automatically started and stopped, and the fault alarm, over-temperature alarm and over-temperature tripping functions are equipped to provide reliable overload protection devices for the dry-type transformer, so as to improve the safety of the dry-type transformer operation.

The establishment of a new centerline – grounding in the 100KVA dry-type transformer can eliminate the problem of common mode interference and other centerlines in the power grid, and the 100KVA dry-type transformer converts the three-wire △ wiring into a four-wire Yo system, and the shielding further eliminates the internal connection by the 100KVA dry-type transformer Coupling high-frequency pulse interference and noise, although the shielded 100KVA dry-type transformer can effectively prevent all kinds of N-G interference (pulse and high-frequency noise), but the 100KVA dry-type transformer must be properly grounded, very strict, otherwise anti-common mode Interference will have no effect. The company can design and produce high-quality 100KVA dry-type transformers for customers.
