1. When assembling and adjusting the appearance, the original position should be recorded for rehabilitation. 2. When repairing the appearance of precision instruments, if you accidentally bounce small parts away, you should first determine the position where you can fly down.

1. Aluminum alloy shell or steel plate welding, plastic spraying on the surface; 2. Built-in inverters, circuit breakers, signal lights and other components produced by domestic or Schneider and other companies; ​ 3. It mainly regulates the general three-phase difference by changing its output frequency.

1. Check whether the appearance of the inverter is in good condition, including whether the indicator light is running normally, whether the task control function of the operation panel is complete, and carefully observe the appearance of the inverter in the operating state, and do the corresponding recording work; When repairing the inverter, check whether the voltage value and current value exceed the allowable ...

The air switch is divided into the upper inlet line and the lower inlet line of the power supply, 1 is - 3 is + 2 is + 4 is - when the upper line is inlet, 2 is + 4 is - This is related to the internal trip curve. DC circuit breaker is used for DC system operation method conversion or fault removal ...

1. About the management of higher harmonics on the output side of the inverter The magnetic noise skills brought about by the communication harmonic components contained in the output waveform controlled by PWM control have been increasingly used in various inverters, such as the selection of higher frequency switching components, the installation of filter devices at the output end of the inverter, etc.

(1) Protective button: a kind of button with a protective shell that can prevent the internal button parts from being mechanically damaged or people touching the live part, and its code is H. (2) Dynamic break button: Under normal conditions, the switch contact is a kind of button that is turned on. (3) Dynamic button: Under normal conditions, the ...

(1) When placing signal cables with different properties into the same conduit, they must be isolated (2) Try to avoid accommodating multiple power cords in the same conduit. When it is necessary to set up, a partition should be placed inside the conduit and the partition should be grounded. ...

(1) The operation circuit compares the external speed, torque and other instructions with the current and voltage signals of the detection circuit to determine the output voltage and frequency of the inverter. (2) The voltage and current detection circuit are the same as the main loop potential ...

The foot switch series is XPE, and it should be noted when selecting: 1) Raw materials: metal and plastic, which are used in heavy-duty, high-risk, light-duty, low-risk occasions. 2) Pedal: divided into single pedal and double pedal (type end plus D). 3) With or without maintenance cover ...

Schneider Barrier Features: First of all, Schneider Barrier Switch can be used to block the power supply, it can disconnect the live equipment from the high-voltage maintenance equipment, and it can also see a significant disconnection point on it. The second is that Schneider Barrier Switches are able to work with circuit breakers to reach the point where the operation of the system is changed.

1. Copy and copy through the Chinese panel. Older inverters, if they support Chinese panels, such as ATV71, ATV61, etc., support VW3A1101 panels, they can use the proprietary 'open/save as' parameter on the panel to copy and copy, and the newer ATV610, ATV630, ATV930, ...

How to carry out the selection of inverter normally, is the difficulty faced by many enterprise technical personnel and business personnel, in addition, the selection of the inverter body alone, without considering whether the inverter selection and capacity matching is appropriate, is also unscientific. ...

Fundamentals of magnetic flux vector manipulation The control of a three-phase asynchronous motor is much more complicated than that of a DC motor because the current, voltage, induced potential, magnetic flux, etc., of the stator and rotor are all alternating. However, the stator winding of the three-phase asynchronous motor is a symmetrical three-phase winding, which exerts a ...

There are many series of contactors: LC1-SK series: below 6ALC1-K series: 6A-16ALC1-D series: 9A-150ALC1-F series: 115A-800ALC1-B series: 750A-1800A When installing, it should be in accordance with the regulations...

The appearance of the instrument plays a very important role in the air separation equipment and gas purification process, and it is indispensable for the adjustment of the air separation process and the detection of product quality. Because there are different types of on-line profiles for monitoring targets in different gaseous media at each stage of the ASU process, the ...

1. Definition of miniature circuit breaker The electrical occupation is referred to as MCB, which is suitable for communicating 50/60Hz additional voltage 230/400V, additional current to 63A line overload and short circuit maintenance, and can also be used as infrequent operation conversion of the line under normal circumstances. ...

GENEVA – Rebecca Lowell Edwards, who has been with the International Olympic Committee for the past 18 months·· has joined Schneider Electric as the company's first global communications chief. In the new work that starts today, love ...

In order to ensure that the APCUPS power supply can continue to provide high-quality power to the computer in the event of a power outage, it is particularly important to equip the battery backup battery. When the frequency load does not agree to be supplied with power, the backup time of the UPS battery in the communication room should be greater than the time from the suspension of the mains power to the recovery or until the generator set is normal.

The orifice flowmeter is a high-range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter), which can measure the flow rate of gas, steam, liquid and natural gas. Widely used in petroleum, chemical, metallurgy, electric power ...
