I. Overview

ADA type electrified railway 27.5 (25) KV AC-DC power supply railway equipment is my company to develop and produce a new type of split-phase uninterruptible power supply products safety regulator. This product has stable performance, reliable quality, reasonable structure, convenient use for electrified railway communications, signal and station house to provide safe and reliable three-phase 380V and 220V single-phase AC power supply, is an advanced and ideal online sine wave uninterrupted power supply system. It was electrified railway from 27.5 (25 ) KV traction line drawn by 25 / 0.23KV obtain single-phase 220V power transformer, when the single-phase 220V power supply voltage dramatic changes, the product of the input voltage can be adjusted continuously, filtering, Steady converted into a DC voltage, then reverse into a three-phase 380V and 220V single-phase AC power supply, and in 27.5 (25) KV pulling wire or single-phase long, when short-term step-down transformer fault, powered by an internal battery and continues to reverse into a three-phase 380V single-phase 220V AC power to the load, and can reach the standard three-phase AC waveform, frequency accuracy, voltage stability. This product is the power supply of the three indicators improved uninterruptible power supply security. It can be for your communication, signal and field stations and other electrical equipment to provide reliable, high-quality three-phase AC power.

Third, the normal working conditions

a) altitude ≤2000m (altitude limit up to 4000m)

b) class Ⅰ ambient temperature -20 ℃ ~ 40 ℃

Ⅱ class of -40 ℃ ~ 50 ℃.

Within 24h average temperature does not exceed 35 ℃

c) relative humidity ≤90% (25 ℃ when)

Note: The special operating conditions agreed by both supply and demand execution

Fourth, the main technical indicators

1; Input; Output Voltage

Single-phase input voltage fluctuations 220V ± 44V, the output voltage at 380V single-phase three-phase 220V

2, the output frequency

Output frequency accuracy was 50 ± 0.05HZ

3, the output waveform distortion rate

Three-phase sine wave output, waveform distortion rate of less than 5%

4, to maintain normal power supply time

Under no input state; AC-DC power inverter railway equipment to maintain normal output voltage; frequency; waveform and the rated power of time is 1 ~ 90min (such as extension of time is determined based on user requirements)

5, temperature control

a) When the AC-DC power inverter equipment cabinets railway the upper temperature greater than 40 ℃, the cooling system starts automatically within the device

b) When the AC-DC power inverter equipment cabinets railway the upper temperature is less than 0 ℃, automatic heating system starts inside the device

6, automatic control

a) AC-DC power inverter railroad equipment has both charge the battery, float and automatic discharge function

b) AC-DC power inverter equipment railway reservation intelligent remote monitoring and management capabilities Interface
