SBW-QZ series elevator and lifting machinery special voltage regulator is a personalized series of industry-specific voltage regulator tailored for users in this industry based on years of experience in designing and manufacturing voltage regulators, for the characteristics of frequent start and stop of elevators and lifting machinery equipment, large impact current, and high user requirements for electricity safety. The special voltage regulator for elevators and lifting machinery equipment has the characteristics of strong resistance to overload impact, high reliability, and long-term continuous cycle operation. SBW-QZ series elevator and lifting machinery special voltage regulator is a personalized product tailored for users in this industry, mainly used for elevator equipment supporting in hotels, hotels, hospitals, business centers and other occasions where the power supply conditions cannot meet the requirements; At the same time, it is also suitable for lifting equipment in mining, heavy machinery and other occasions for stable power supply. SBW-QZ series elevators and lifting machinery special voltage regulators should be used indoors, and the normal use conditions are: 1. Ambient temperature: -10°C—+45°C 2. Altitude: <1000M 3. Relative humidity: 20%-90% 4. There are no gases, vapors, chemical deposits, dirt and other explosive and corrosive media that seriously affect the insulation of the voltage regulator. 5. There is no serious vibration or bump in the installation site.
Basic indicators | Protection function | ||
Input voltage | 380V± 20% or wide voltage is specially defined | Overpressurized | If the output exceeds the rated voltage by 10% (adjustable), the output power supply will be cut off with a delay of 3-5 seconds |
Output voltage | 380V ±5% can be selected | Underpressure | If the output exceeds the rated voltage by -15% (adjustable), the delay will be 3-5 seconds to cut off the output power |
Voltage regulation accuracy | 1-5% can be set | Time delay | Cut off the output power supply for 2 seconds |
frequency | 50Hz/60Hz | Short circuit | When the load equipment is short-circuited, cut off the output power supply |
Response time | ≤0.05s | Passing through | When the rated output current is exceeded, the output power supply is cut off with a delay of 3-5 seconds |
Stabilization time | When the input voltage changes by 10% relative to the rated value, the stability time ≤ 1s | Reverse phase | When there is an error in the three-phase electrical sequence, the machine alarms and cuts off the output power supply (configurable) |
Lack of phase | When the three-phase power is out of phase, the machine alarms and cuts off the output power | ||
Bypass | When the voltage regulator fails or is repaired, it has a manual or automatic pass-through device for power supply | ||
Other indicators | |||
Additional waveform distortion | ≤0.1% | Pressure resistance | The whole machine has no breakdown and no flying arc phenomenon at 2000VAC/min to the ground |
Noise | ＜55dB | Insulation resistance | The whole machine has a ground ≥ of 2MΩ |
efficiency | More than 95% for less than 50KVA, more than 98% for more than 100KVA | EM filtering device | Effectively filters out harmonic interference from the grid (optional configuration) |
Relative humidity | 20%-90% | Lightning protection device | When the power grid changes instantaneously and induces lightning strikes, it can play a role in inrush current protection (optional configuration) |
Working methods | It can work continuously unattended for a long time | monitoring interface | With R232 and RS485 interfaces, remote control, remote signal, and telemetry functions (optional configuration) |
