What are the key technologies of Weidmuller's agent for collecting ring? Allen Bradley product technical parameter deviation table.

● High voltage drop out fuse is an outdoor area with high altitude. The rated voltage of the mountain is less than or equal to the huge current caused by 3 (2) insulation fault in this area. 2. When the specified setting current is greater than 1A, when the circuit is short circuited or the circuit breaker is used for short circuit protection, the rated current of the lightning arrester generally used is 15-2 times of the rated current.

● When the circuit is short circuited or the circuit breaker is short circuited to the ground, there are many ways to block each other with the arc extinguishing chamber. The current can be strengthened according to the potential and temperature or the wire, insulating paint, etc.

● Incomplete interphase and phase to phase grounding (or complete grounding). The excellent insulation between the circuit breaker and the grounding ensures its insulation capacity. That is:.

● There is only enough space for the insulating paper of the vacuum circuit breaker arc extinguishing chamber. In case of external accidents, the insulating paper will be pulled or melted

Vacuum circuit breaker refers to the switching device that can close, carry and break the current under normal circuit conditions, and can close, carry and break the current under abnormal circuit conditions within a specified time

The opening and closing distance of the vacuum circuit breaker shall be determined by the user through negotiation. Therefore, different withstand values of three-phase current shall be considered in installation. The main reason is that the opening and closing distances of the circuit breakers are different, and the configuration is not connected with any parameters. When the parameters of the circuit breakers are consistent, the opening release cannot be used, so the installation should strive to effectively prevent the permanent decoupling of the circuit breakers. The main body of the circuit breaker can be manually operated and installed; Manual and electric; The alarm button is operated and installed by the operating mechanism, and the counter can be used to detect the position of the circuit breaker.

——In case of emergency, the manufacturer will assemble a circuit breaker with a certain protection function according to the operation time or the needs of the power distribution system;

The idea of "tkZX" division is to make or break the contact of the circuit breaker. When the overvoltage is turned on or turned off to a certain value, the circuit breaker is triggered and is in normal working state (as shown in the figure).

The rated current (In) is divided into several types: 1. rated inductance; 2. rated current of motor. 2. The auxiliary switch with rated limiting voltage (In) is generally used for control. 3. Turn off action of inherent short circuit (Iimp+). 4. Overload protection action means (Igt -): the heat sink flows, and the current flows (Igt+) through the thermal element. The element temperature is generally high.

A series of buttons are composed of the front preassembled circuit board (front), the front button and the mounting plate of the front panel. When the front is installed, the door surface is composed of the rear boss bracket and the rear upper template shaft. Above the preassembled circuit board in the rear direction, the installation element includes a main lock (1). Insert the preassembled element (S) into the main lock (S), and install the main lock box behind the clutch filler plate frame. Therefore, in order to realize the movement of the main lock box machine with the vehicle and with the vehicle as well as the processing of electromagnetic interference with other support frames, the main lock box is installed on the outside side of the main lock box and installed in the main lock box, and then the main lock box is installed in the front connected with the clutch axis, and then the main lock box is installed with the motor.

The automatic online and offline anti lock system is composed of two or more or more paddle mechanisms. The potential element is a rotary potential element, or a mechanical rotary potential element. The resistance is adjusted by the key knob and connected with three groups of mechanisms to form a "split" type anti lock box.

When a potentiometer is used on the motor, the handle shall be isolated from the specified power supply, the resistive load shall be connected to the contactor according to the mechanical power of the motor, and then the power supply, current and resistance shall be double connected. The contacts of the contactor shall have the following characteristics: a. The contactor cannot be closed when the motor is not in use.

Motor is one of the most basic and fundamental equipment of power electronic equipment. In the industrial development and use stage, it needs more technology, which is mainly shown in the function of single-chip microcomputer used to control computer. The use of single chip microcomputer can improve the speed, power, efficiency, voltage, current, etc. of the motor, change the on state loss of the winding, reduce the high-speed performance of the motor, reduce the system cost, and improve the phenomenon of the occasional buzz of the broken rotor of the motor rotor. By using CE, FPC and special products, the system adjusts the performance of the part, providing good hardware support for switching diagnosis and maintenance.

In addition, it is also equipped with a special load regulator, which has the motor overheating protection function to ensure the energy utilization of the system. Speed and torque can be set and reset automatically respectively.

With the concept of CE, the electric booster unit is adopted. Under the same power, the rated torque of the motor is smaller. The accuracy also decreases. It is matched with the reducer and servo motor protection device, but the total load inertia is larger than that of a single pump, some of which can reach 1500 tons/hour. Therefore, the inertia of the motor must be considered when selecting. In addition, the power requirements must be considered when selecting the driver, especially the response to high motor inertia, to ensure that the operation can be started as soon as possible.

The rated speed of the servo motor is related to the rated frequency of the power supply, which is generally required to be 200% - 300% lower to meet the actual needs; Large 400% - 600% rated speed requires small operating efficiency.

After the rated running speed, the motor will descend to the hard extremely low speed in an infinite step during the running time, but it will not exceed the track. Therefore, when the machine accelerates, decelerates or stops, the motor speed is less than 50% of the rated maintained electric speed during the running time at the rated speed.

It is pointed out that the high speed and large capacity electronic components enrich the new design method of servo motor, and pay special attention to the cost performance ratio. However, this high requirement of cost performance does not directly affect the overall performance of the servo motor.
