基本細節(jié):6SE7023-8TD61-Z+G91 變頻器 電力控制設備

6SE7023-8TD61-Z+G91變頻器是一種電力控制設備，也稱為變頻驅動器或驅動控制器，它通過利用電力半導體器件的通斷作用，將工頻電源變換成另一頻率電源的電能控制裝置。它是現(xiàn)代最先進的一種異步電動機調(diào)速設備，可實現(xiàn)軟起動、軟停車、無級調(diào)速以及特殊要求的增、減速特性等。
變頻器的工作原理主要有交-交型和交-直-交型兩種。交-交型輸入和輸出都是交流，將工頻交流電直接轉換成頻率、電壓均可控制的交流電。交-直-交型則是輸入為交流，先經(jīng)過整流變成直流電，然后再把直流電變成頻率、電壓均可控的交流電。
變頻器在多個領域都有廣泛的應用，包括但不限于冶金礦山、建材應用的破碎機類負載，大型窯爐煅燒爐類負載，壓縮機類負載，軋機類負載，卷揚機類負載，轉爐類負載，輥道類負載，以及生產(chǎn)鋼絲的拉絲機類負載等。

變頻器的優(yōu)點主要包括：
節(jié)能效果好：變頻器可以根據(jù)負載需求調(diào)節(jié)電機轉速，使電機高效運行，減少空載和低載時無效功率消耗，具有很好的節(jié)能效果。
調(diào)速范圍寬：變頻器輸出頻率在0-400Hz非連續(xù)調(diào)節(jié)，電機轉速可按需求連續(xù)調(diào)節(jié)，調(diào)速范圍寬。
具有恒轉矩特性：變頻器可以在電機轉速改變時使轉矩保持不變，適用于要求恒轉矩的場合。
對電機保護好：變頻器可以限制電機起動電流和功率，實現(xiàn)軟啟動，減少對電機絕緣和機械的損壞。
使用靈活方便：變頻器參數(shù)設定靈活，控制方式多樣，使用方便，與PLC、DCS集成方便。
運行可靠性高：變頻器采用數(shù)字控制，硬件可靠性高，且無觸點磨損問題。
成本效益高：變頻器省電效果顯著，安裝和維護費用低，使用壽命長，具有較高的成本效益。

6SE7023-8TD61-Z+G91 inverter is a power control device, also known as frequency conversion driver or drive controller, it converts power frequency power supply into another frequency power supply power control device by using the on-off action of power semiconductor devices. It is a modern most advanced asynchronous motor speed regulation equipment, can achieve soft start, soft stop, stepless speed regulation and special requirements of the increase and deceleration characteristics.
The working principle of the inverter mainly has two types: ac-AC type and AC-direct-AC type. The AC-AC input and output are AC, and the power frequency AC is directly converted into the frequency and voltage can be controlled. Ac-dc-ac type is the input AC, first rectified into direct current, and then the direct current into the frequency and voltage are controllable alternating current.
Inverter has a wide range of applications in many fields, including but not limited to metallurgical mines, building materials applications crusher load, large kiln calcination furnace load, compressor load, rolling mill load, hoist load, converter load, roller table load, as well as the production of wire drawing machine load.

The advantages of the inverter mainly include:
Good energy saving effect: the inverter can adjust the motor speed according to the load demand, so that the motor can run efficiently, reduce the invalid power consumption when no load and low load, and has a good energy saving effect.
Wide speed range: the output frequency of the inverter is not continuously adjusted at 0-400Hz, the motor speed can be continuously adjusted according to demand, and the speed range is wide.
With constant torque characteristics: the inverter can keep the torque unchanged when the motor speed changes, which is suitable for occasions requiring constant torque.
Good protection of the motor: the inverter can limit the motor starting current and power, achieve soft start, and reduce the damage to the motor insulation and machinery.
Flexible and easy to use: frequency converter parameter setting is flexible, control methods are diverse, easy to use, easy to integrate with PLC and DCS.
High operational reliability: Frequency converter adopts digital control, high hardware reliability, and no contact wear problems.
High cost efficiency: The inverter has remarkable power saving effect, low installation and maintenance costs, long service life, and high cost effectiveness.
