　　無(wú)旁路型軟起動(dòng)器：在電動(dòng)機(jī)進(jìn)入正常運(yùn)轉(zhuǎn)狀態(tài)后，不使用旁路交流接觸器，而是繼續(xù)通過(guò)軟起動(dòng)器為其提供額定電壓。該類型軟起動(dòng)器常用于短時(shí)且重復(fù)工作的場(chǎng)合。

　　節(jié)能型軟起動(dòng)器：當(dāng)電動(dòng)機(jī)的負(fù)載較輕時(shí)，通過(guò)控制降低電動(dòng)機(jī)的工作電壓，從而減小電動(dòng)機(jī)的電流勵(lì)磁分量，提高電動(dòng)機(jī)的功率因數(shù)，實(shí)現(xiàn)節(jié)能效果。

　　三、工作原理

　　ATS48C17Q 軟起動(dòng)器的主要構(gòu)成是串接于電源與被控電機(jī)之間的三相反并聯(lián)晶閘管及其電子控制電路。通過(guò)控制三相反并聯(lián)晶閘管的導(dǎo)通角，使被控電機(jī)的輸入電壓按不同的要求而變化，實(shí)現(xiàn)不同的功能。在起動(dòng)過(guò)程中，電動(dòng)機(jī)的起動(dòng)電流逐漸增大，直至達(dá)到設(shè)定值，從而實(shí)現(xiàn)平滑起動(dòng)。

　　四、起動(dòng)方式

　　ATS48C17Q 軟起動(dòng)器具有多種起動(dòng)方式，包括斜坡升壓軟起動(dòng)、斜坡恒流軟起動(dòng)、階躍起動(dòng)和脈沖沖擊起動(dòng)等。這些起動(dòng)方式可以根據(jù)負(fù)載情況和電網(wǎng)繼電保護(hù)特性進(jìn)行選擇，以實(shí)現(xiàn)最佳的起動(dòng)效果。

　　ATS48C17Q series soft starter is a kind of device specially designed for the smooth start of the motor, its core function is to control the voltage and current when the motor starts, to achieve a non-impact, smooth start process, to reduce the impact and loss of the power grid, the motor and the mechanical system. The following is a detailed introduction to the series of soft starters:

　　Definition and function

　　ATS48C17Q soft starter is a motor control device which integrates soft start, soft stop, light load energy saving and various protection functions. It can realize the smooth start of the motor without impact during the whole starting process, and adjust the parameters during the starting process according to the characteristics of the motor load, such as the current limit value, starting time and so on.

　　Ii. Types

　　According to different load types and application scenarios, soft starters can be divided into bypass type, non-bypass type, and energy-saving type.

　　Bypass type soft starter: When the motor speed reaches the rated speed, the bypass AC contactor replaces the soft starter to provide the rated voltage for the motor, so as to reduce the loss of the soft starter and extend its service time.

　　Non-bypass type soft starter: After the motor enters the normal operation state, the bypass AC contactor is not used, but the rated voltage continues to be provided through the soft starter. This type of soft starter is often used for short and repetitive work occasions.

　　Energy-saving soft starter: When the load of the motor is light, the working voltage of the motor is reduced by control, so as to reduce the current excitation component of the motor, improve the power factor of the motor, and achieve energy-saving effect.

　　Third, the working principle

　　The ATS48C17Q soft starter is mainly composed of three opposite parallel thyristors and electronic control circuits connected in series between the power supply and the controlled motor. By controlling the conduction Angle of the three opposite parallel thyristors, the input voltage of the controlled motor can be changed according to different requirements and different functions can be realized. During the starting process, the starting current of the motor gradually increases until it reaches the set value, so as to achieve smooth starting.

　　4. Starting mode

　　The ATS48C17Q soft starter has a variety of starting modes, including ramp boost soft start, ramp constant current soft start, step jump start and impulse impulse start. These starting modes can be selected according to the load condition and the relay protection characteristics of the network to achieve the best starting effect.

　　5. Characteristics and advantages

　　Smooth starting: reduce the impact of starting current on the power grid and the motor, and extend the service life of the equipment.

　　Adjustability: Adjust the starting parameters according to the load characteristics and network conditions to achieve the best starting effect.

　　Energy-saving effect: energy-saving soft starter reduces the working voltage of the motor during light load, improves the power factor, and realizes energy saving.

　　Multiple protection functions: overload protection, phase break protection, overcurrent protection and other protection functions to ensure the safe operation of equipment.
