SPV8R-170 Intelligent Soft Start

SPV8R-170 intelligent soft start is widely used in industries such as power, metallurgy, mining, building materials, petrochemicals, and municipal engineering, and is suitable for starting control of small and medium-sized fans, pumps, and general machinery

　　SPV8R-140 Intelligent Soft StartPower 90KW, current 170A, external dimensions 196 * 372 * 236. It is a low-voltage motor control device launched by Songpu Technology. Here is the product information:

Features

Multiple starting methods: There are six starting methods including current limiting starting, voltage ramp starting, jump+current limiting starting, jump+voltage ramp starting, current ramp starting, and dual closed-loop starting, which can meet the starting needs of different loads.

Multiple protection functions: It has multiple protection functions such as overcurrent protection, phase loss protection, three-phase current imbalance protection, overheating protection, motor overload protection, overvoltage protection, load short circuit protection, etc. It also has external fault input protection, voltage loss protection, and long starting time protection, which can effectively protect the safety of electric motors and related production equipment.

Energy saving operation mode: supports intelligent bypass control. After the motor reaches the rated speed, it automatically switches to the bypass contactor for power supply, which can reduce the power consumption of the soft starter by 70% and reduce the temperature rise of the thyristor by 20 ℃; When the load rate is less than 40%, the output voltage can be automatically reduced to 80% of the rated value to achieve light load energy saving.

Communication function: It can provide Chinese upper computer software for users to remotely debug and control, achieving intelligent management.

Display and operation: Large screen LCD Chinese display, convenient parameter setting and query, real-time display of working status, can replace some instrument and digital display functions.

Application field

Widely used in industries such as power, metallurgy, mining, building materials, petrochemicals, and municipal engineering, it is suitable for starting control of small and medium-sized fans, pumps, and other general machinery.

Maintenance and Care

Environmental monitoring: The operating environment temperature should be ≤ 40 ℃, and when the relative humidity is>75%, a molecular sieve desiccant and temperature humidity linkage control system should be used; Install active power filters near harmonic sources such as frequency converters to reduce voltage distortion from 8% to below 3% to ensure the normal operation of the equipment.

Parameter optimization: Dynamically adjust the starting and protection parameters based on the load characteristics. For example, the "current limiting start+torque boost" mode can be used for heavy load starting, and the "ramp voltage start" mode can be used for light load starting. The overload protection level and undervoltage protection threshold should be reasonably set.

Predictive maintenance: Through vibration spectrum analysis, infrared thermal imaging inspection, and other methods, key components of the equipment are monitored, temperature trend charts are established, potential faults are detected in advance, and maintenance is carried out in a timely manner.
