Dry-Type Distribution Transformer Three Phase, 50Hz, 35kv, Power System

Product technical performance
Dry-type transformers

Dry-type transformers have been accepted by more and more users because of their special performance. They are used in various environments such as commercial and residential areas, subways, power plants, ships, and offshore drilling platforms, and places where the conditions of use are harsh. The prospects are very broad. The company absorbs advanced technology from home and abroad, adopts new materials, optimizes design, and designs and produces SC(B)10, SC(B)Z10 two series of transformers, which are widely used in three-phase, 50Hz, 35KV and below power systems. , is the main power equipment of 35KV and below power grids for industrial and agricultural distribution, power and lighting.

The SC(B)10 and SC(B)Z10 series transformers produced by the company are developed by introducing foreign advanced technology. The high-voltage coils are wound by segmented double-glass envelopes and poured under vacuum to prevent coils. Internal bubble generation, so the partial discharge capacity fully meets the relevant national standards; the copper foil width of the low-voltage winding is the reactance height, the low-voltage current is matched according to the ampere-turn balance requirement between the windings, and the axial force caused by the short circuit of the high-voltage and low-voltage windings Almost zero; our company's SCB10, SC(B)Z10 series transformers adopt filler resin and all-copper structure. The coefficient of thermal expansion of insulating material and copper conductor is very similar, effectively preventing the cracking of the coil and ensuring the change in temperature, temperature and temperature. It is used in a wide range of occasions, and can meet the anti-cracking requirements after long-term operation; this series of transformers are maintenance-free, moisture-proof, heat-resistant, flame-retardant, and self-extinguishing; under the high-temperature combustion of the arc, no toxic gases are produced. The SCB10, SC(B)Z10 series have a total loss reduction of 10% to 15% on average compared with the "9" type products commonly used in China, and have good economic benefits.

The SC(B)Z10 series transformers produced by the company adopt the advanced SPK-B3 vacuum on-load tap-changer. This type of switch has advanced structure, reliability, low failure rate and intelligent control. The on-load tap-changer and the on-load tap-changer for vacuum power supply are composed of on-load and pressure-regulating systems to ensure that the equipment power voltage is stable within a certain range. The use of electrical equipment works normally, reduces losses, reduces costs, and improves some electrical devices. Life expectancy.

The other structural features of the company's dry distribution transformers:
1, Iron core: iron chip adopts high-quality 30QG120 grain-oriented cold-rolled silicon steel sheet. The iron core adopts fully inclined multi-step joints and no punching type; the surface of the iron core is coated with resin paint, making the iron core a whole, and greatly Reducing the noise of iron cores; clamping method using clamp rods and epoxy glass ribbons;
2, Using high-performance silicone pads, to prevent mechanical resonance, reduce noise;
3, Shell: shell protection grade classification according to GB4280 standard. Generally without shell protection, namely IP00, according to user requirements, generally can be installed to protect the IP20, IP23 and other protection grade requirements of the shell, shell materials are steel, aluminum and stainless steel. When the outer shell is made of steel plate, it is painted according to the user's selected color. There are doors on the front and rear walls of the enclosure for user maintenance. There is an opening in the cable entrance so that the cable can pass through and there are removable windows on both sides and on the top to facilitate the connection of the copper bar to the switchgear cabinet.
4, Security protection device: in accordance with the national standard JB/T7631 configuration: cooling fan, temperature controller; if the user requirements, the transformer can be configured: cooling fan, intelligent temperature controller, humidity controller and other safety protection devices.

 Use environment:
1. Altitude: ≤1000 meters;   
2. The ambient temperature: the highest temperature +50 °C, the highest monthly average temperature +35 °C;The lowest temperature -50 °C, the highest annual average temperature +25 °C;
3. Installation environment: The inclination of the installation site is ≤ 3°, no obvious contamination, corrosion, and Flammable gas.
