SZC(B)-10 SZC(B)-11 SZC(B)12 SZC(B)13 series intelligent 3 -Phase indoor dry-type Distribution transformer

Short Description:

  • This product conforms to the national standard GB1094.1-2013(IEC 60076) power transformer and GB / T6451-2015 indoor dry-type transformer technical parameters and requirements.
  • Epoxy resin pouring transformer is a solid insulation encapsulated winding power transformer.
  • Epoxy resin dry-type transformer uses epoxy resin as insulation material.High and low voltage winding is made of copper strip (foil), epoxy resin is poured and solidified in vacuum to form high strength FRP body. Insulation grade is F and H.
  • Epoxy resin dry-type transformer has the characteristics of good electrical performance, strong lightning shock resistance, strong short-circuit resistance, small size and light weight etc.. The temperature display controller can   be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer.

Product Detail

Product Tags

Compared with the manual voltage regulation of traditional SCB series indoor dry 3-phase power transformer, SZC(B)-10  SZC(B)-11  SZC(B)12 SZC(B)13 series  intelligent 3- Phase indoor dry-type Distribution transformer can realize the load through the controller on the ground remote power transformer to adjust the voltage, which can realize free power voltage regulator, reducing frequency of climbing and risk, greatly convenient for power operation personnel on site.

PERFORMANCE CHARACTERISTICS

1. No oil, no pollution, flame retardant, self-extinguishing and fire prevention.

2. Low loss, high efficiency and low noise. It can run long time under 125% rated load under the forced air-cooling condition and is equipped with intelligent temperature controller. The functions of fault alarm, over temperature  alarm, over temperature trip and black gate. It is connected with computer through RS485 serial interface and achieves centralized monitoring and control.

3. Small local discharge (under 30 PC) and high reliability, can ensure long-term safe operation, life up to 30 years.

4. Resistance to crack and temperature change, high mechanical strength, strong ability to resist sudden short-circuit.

5. Good moisture-proof property, it can run normally under 100% humidity and can be put into operation without drying treatment after shutdown.

6. There is no need for a separate transformer room, core maintenance or load-bearing beam  saving civil land and occupation No oil, so it will not produce toxic gas to pollute the environment.  No need of oil collecting pits or other ancillary buildings which reduces the cost of construction Easy installation, no debugging, almost no maintenance; No need to replace or check the oil, low operation and maintenance cost.
