How can Allen Bradley PLC products break the situation?

2023-01-02

With the rapid development trend of electric power engineering, there are many types of outdoor vacuum circuit breakers in China. How can we distinguish them? How can Allen Bradley PLC products break the situation?

Not necessarily, but the type, structure and working principle of vacuum circuit breaker correspond to that of vacuum circuit breaker. (1) The main circuit of the permanent magnet synchronous motor is controlled by the electromagnet that changes from permanent magnet (AC) to AC (DC) excitation (DC) excitation. In the control cabinet, the primary side current (generally 1A) must be obtained, and the magnetic circuit must increase or decrease the excitation current through the loop secondary magnetic circuit in the control cabinet. (2) The magnetic circuit is saturated. (3) The maximum operating frequency shall not be less than 02Hz. (4) The magnetic circuit is saturated.

Initial reagent current value caused by coil short circuit. (5) Series connection of y, z of y (also called primary stage) applies or removes counterclockwise y, z application loop.

If the short-circuit breaking capacity and imbalance degree of the circuit breaker are not considered, that is, the short-circuit multiple between them should not be too large;

"Three phase voltage", "Three phase current", "Pulsating current", "Eleven phase current", "Twelve phase current", etc;

The circuit breaker refers to the switching device that can turn on, carry and break the current under normal circuit conditions, turn on, turn on and break the short-circuit current within a specified time, and carry and break the current under abnormal circuit conditions within a certain time. Circuit breakers are divided into high voltage circuit breakers and low voltage circuit breakers according to their scope of use. The high and low voltage boundaries are relatively vague, and those above 3kV are generally referred to as high-voltage electrical appliances.

At present, as the main component of the circuit breaker, the circuit breaker is usually a semi qualitative one, equipped with electromagnetic clutches below 40A and above. Its wiring mostly adopts column structure, which can be matched with 16A, 10A below and 6A above. The circuit breaker has instantaneous tripping function, large breaking capacity, and tripping function when rated short circuit is short and breaking speed is high. It can be used universally when there is a thermal/circuit breaker. It can be used as instantaneous tripping protection, and the setting current can be determined according to the matching current or current size. The rated working current, breaking time and tripping function of the rated working and rated short time are selected according to the performance.

Overload protection, disconnection protection, grounding protection, locked rotor protection. The tripping grade is IP54. The rated current is 2A. The tripping grade is IP23/IP20.

The breaking capacity, rated current 40A-160A and below thermal overload relay of the circuit breaker is applicable to 150A-200A, which is generally applied to 55KW and below motor protectors. It has the functions of double winding, automatic reset of rear section, automatic reset of short circuit, automatic reset of short circuit and product upgrade. In case of any abnormality, the circuit breaker will automatically cut off the circuit after a delay to protect the motor from inrush current or overload and realize the overload protection function.

Thermal overload relay is mainly used for AC 50Hz or 60Hz, rated voltage 380V and other motor overload protection.

Motor phase loss protection device, in order to prevent AC stall and overload, the water pump is subject to phase loss operation. It is divided into liquid level protection floating differential pressure indicator and liquid level indicator.

When the working pump starts, the flow indicator outputs the working state, and the belt stops flowing at the same time. When the working pump stops, the inverter outputs the posture, and the relay contacts the motor,

The liquid pressure control is determined by the output frequency controlled by the frequency converter. The speed of the motor is adjusted by the frequency converter to achieve the purpose of adjusting the flow. When the fluid with small flow is required to enter the device, the flow indicator can control the speed of the motor according to the set flow, so as to achieve accurate flow control. When the water consumption changes, the cooling pipe drop will also automatically drop and heat dissipation loss. The heat dissipation effect can be achieved by reducing the hose diameter of the pump, and the energy-saving benefit is very considerable.

Shanghai's high-quality PID control and advanced contactless electronics are characterized by long service life, high accuracy, high control accuracy and simple operation. They are equipped with pressure start and stop button switches. Use reasonable control software to ensure that the control parameters are independent of the target value and productivity.
