Suitable for all working conditions! Application scenarios and Industry NRRQV high-voltage solid-state soft starter

The working environment of industrial HV motor is complex and varied. Load characteristics, starting environment and power supply conditions are obviously different in different industries. The common starting equipment will often encounter problems of starting fault, the fluctuation of the net frame, the wear and tear of the equipment and frequent operation and maintenance. NRRQV high voltage solid-state soft starter adopts thyristor stepless voltage regulation technology, all-solid-state maintenance-free structure, intelligently adjusts starter curve, and is adaptable to working conditions. Suitable for all kinds of complex industrial scenarios, such as light load, heavy load, high temperature, low temperature, dusty, continuous start and stop. Widely used in multiple industries such as high voltage fan, water pumps, crusher, compressor and other major equipment, is a high voltage motor control and protection device.
Hydraulics industry is the core of NRRQV soft starters adaptation scenario, mainly used for high voltage water water supply pumps, drainage pumps, sewage pumps, flood pumping stations and other equipment. Most of these types of devices are light weight or stable in load, but boot up is frequent and device intensive. Direct starting is easy to cause water hammer impact on pipeline network, which leads to pipeline vibration, interface loosening and pipe cracking. NRRQV can achieve a smooth start, effectively reduce water hammer effect, protect pipeline network and pump structure, stabilize the power grid voltage factory area, and avoid power grid fluctuations caused by the start and shutdown of multiple units. The equipment is waterproof, dust-proof, moisture-proof structure, fully adapted to the harsh working conditions of wet pump stations, suitable for 3kV to 10kV high pressure pump units.
The mining and metallurgical heavy industry has outstanding advantages in adapting to heavy working conditions, mainly used in mine ventilation fans, hoist, crusher, sintering fan, metallurgical air compressors and other heavy equipment. The device has high starting resistance and high load torque. Traditional hydraulic resistance starting and the autocoupler start have insufficient starting torque, so it is easy to stall and start fault. In addition, heavy starting shock can easily damage transmission components such as gears and bearings. NRRQV supports the special starting curve of heavy load, can accurately adjust the starting voltage and start time, establish enough low-speed torque to drive the heavy load equipment smoothly, and eliminate the problem of locked rotor tripping. At the same time, the equipment has no perishable parts, is high temperature and dust resistant, and is completely adapted to the harsh working conditions in mines with high dust, high load and 24-hour continuous operation.
Chemical industry, petroleum, building materials industries to equipment stability and grid safety requirements are extremely high, makes a key application area of NRRQV. High-power equipment such as high-pressure compressor, reaction kettle mixer, oil pumps, cement mills, rotary kiln fan and material hoists have the characteristics of high power and multi-unit in chemical production line and building materials. Centralized start-up is easy to cause voltage drop and protection misoperation factory power grid, which affects the operation of precision instruments and automation equipment. NRRQV can keep the starting current in a reasonable range without any sudden drop in current or voltage, ensuring the purity and stability of the production line power grid. The equipment is corrosion resistant and high temperature resistant, suitable for high temperature, corrosion and continuous production conditions in chemical industry.
In the fields of electricity, papermaking and public infrastructure, the equipment is highly adaptable to NRRQV's maintenance-free advantages, such as high start-up downtime frequency and strict continuous operation requirements. Inductive fan, supply fan, circulating water pumps of thermal power plant, high pressure pulping equipment, ventilation equipment of paper mills, as well as tunnel exhaust fans, fire fighting high pressure pump, large central air-conditioning unit and other infrastructure equipment, running continuously throughout the year. Traditional start-up equipment is cumbersome to maintain and has a high failure rate. NRRQV adopts all-solid-state electronic structure, no mechanical wear and tear, no electrolyte consumables, basically no routine maintenance, greatly reduces the operating and maintenance pressure of unit. At the same time, it supports multi-use time start, adapts to multi-device centralized control scenarios, and saves equipment investment and distribution space.
With flexible starting parameters, comprehensive intelligent protection and reliable environmental adaptation capabilities, NRRQV high-voltage solid-state soft starters covers most high-voltage motor application scenarios such as light, heavy, municipal and energy. It can not only adapt to light load and stable start, but also to heavy load and strong starting, and can also adapt to harsh industrial environment and standardized and clean working conditions. NRRQV has the core advantages of high condition adaptation, good stability and low operating and maintenance cost.
