Pump-specific soft start cabinet

Features: Reduce the starting current, reduce the impact of starting equipment on the grid; reduce motor wear and tear, improve the life of mechanical transmission equipment; smooth acceleration of the load can reduce mechanical shock, prevent production accidents or damage to the product; the use of soft Stop function, the load can be slowed down to eliminate the pump load water hammer effect. ● A variety of starting methods Voltage ramp start, current limit start, ramp + current limit start, and in each mode can be applied to the programmable kick start torque. The unique basic algorithm makes the motor start, stop more accurate and smooth. ● Advanced communication function Equipped with RS485 communication interface to facilitate user network connection control and improve the system's automation level and reliability ● Practical analog signal control function Users can input 4 ~ 20mA or 0 ~ 20mA standard analog signal, and can be operated Panel on the simulation of the upper and lower limits set to achieve the motor starting and stopping control and alarm. Soft starter can also be carried out by the data (pressure, temperature, flow, etc.) of the transmission. ● Strong anti-interference performance All external control signals are optoelectronic isolation, and set a different level of anti-noise, suitable for use in special industrial environments. ● Unique dual-parameter soft starter also has two sets of different power motor control parameters, can control two different power motors. ● Three kinds of parking soft programmable parking, free parking, parking brake. ● protection display full detection of current and load parameters, with over-current, overload, overheating, lack of equivalent computer protection. ● friendly man-machine interface with LCD LCD Chinese display operating box, making programming and adjustment more convenient. Fault and real-time monitoring more intuitive and improve work efficiency. Pump-specific soft starter cabinet Scope of application: 1, the device is mainly used for industrial, agricultural, domestic water, sewage and fire water supply and other occasions. 2, the device is suitable for a variety of high-power pump motor start running. 3, the device can be equipped with a variety of automated instrumentation for automatic control. Such as multi-pump control, level control, regular water supply, fire water supply, water protection and so on. Pump-specific soft-start cabinet works: Three-phase induction motor in the direct start, have a large starting current. Depending on the motor, the starting current range is approximately 3 to 10 times the rated operating current and the typical starting current is 7 to 8 times the rated motor current. Such a large current has many adverse effects on the operation of the power grid and the equipment. JSYR series soft starter cabinet is designed for submersible pumps and a digital intelligent start device. It applies microprocessor and transistor technology to the start and stop of three-phase induction motors in combination. It uses the principle of voltage slope to control the voltage output to the motor from a settable initial value through a settable ramp time up to Full voltage supply grid. Water pump special soft starter cabinet Model Description: Dedicated water pump soft start cabinet System Installation: Installation Environment: Ambient temperature -20 ~ 50 ℃, non-condensing, relative humidity Power Requirements: 660V ± 10%, unbalanced ≯3%, 50Hz ± 2 %. Pump-specific soft-start cabinet Technical Specifications: Starting method: voltage ramp, starting time 5-60 seconds. Parking: soft parking (5-60 seconds) or free parking. Starting and stopping times: no more than 20 times per hour. Power range: 15-315KW three-phase asynchronous motor. Product wiring: The main circuit wiring: the power cord connected to the upper end of the power circuit breaker, the motor line through the transformer connected to the U, V, W three copper. Grounding protection should be the same cross-sectional diameter connected to the ground bolt, and good grounding to prevent accidental electric shock. Liquid Level Probe Installation and Wiring: When the product is shipped, the control terminals 045 and 047 are short-circuited, the control panel is manually / automatically set to auto, and the soft-start does not start. When it is needed, remove the short wiring and connect the high water level probe Then 045, the water level probe connected 046, low water level probe connected 047, according to the following probe set to place the probe can be realized automatically Sheung Shui. Probe settings: the probe will be low to the bottom of the water tower, water tower, respectively, according to the water supply range set high, when the system due to lack of water boot water level rose to the center will not stop until high will stop, and the water tower full indication, when the water level again Below high, the system will not boot immediately, only to lower than the median will automatically boot. Water pump dedicated soft start cabinet system debugging: AAAV voltage conversion standby operation indication Fault indication water full indication start stop Manual / automatic emergency stop panel cabinet as shown on the right: Before starting components should be checked for damage loose, the left side of the cabinet The boat switch should be set to OFF position, motor protection setting value is in the specified value, then set the panel to the right position, and according to the product wiring instructions connected to the line, turn on the power, close the circuit breaker, see the soft starter The parameters are correct, if everything is normal, you can start the device. At this point, automatic manual set manually, press the start button soft starter will be put into operation. Soft start from the set voltage (1M01), within the start-up time (1M00) slowly rose to full pressure, then bypass the output, KM contactor pull, running light, motor full pressure run, the soft starter exit the output; Press the stop button, the soft full-pressure output at the same time open the bypass (KM contactor off), then soft from full pressure soft stop time (1M04) slowly dropped to 0V, soft stop completed. To avoid accidents, the system has an emergency stop button in the cabinet and the scene there are emergency situations through the emergency stop button to power off the system to avoid further expansion of the accident. The left side of the cabinet has a boat-shaped switch, mainly used for fault diagnosis and emergency treatment, such as to confirm the soft fault, water pump trouble-free temporary water can be used to set the boat-shaped switch ON bit, the normal operation should be set OFF.
