Tianyi switch - precautions for the use of proximity switches

It is mainly divided into ATS and STS. STS static toggle switch STS (Static Transfer Switch), also known as static transfer switch. The STS automatically switches to the second channel to supply power to the load after the first channel fails.

1. The high-voltage load switch can be broken with load and has the function of self-extinguishing arc, but its breaking capacity is very small and limited. 2. The high-voltage isolation switch is generally not able to break with load, there is no arc extinguishing cover in the structure, and there is also an isolation switch that can break the load.

1. Pay attention to stability When adjusting the output current of the switching power supply, the stability of the circuit must be ensured, otherwise there will be current fluctuations, disturbances and other phenomena, which will affect the normal operation of electronic equipment. Therefore, it is necessary to perform a ...

1. What are the common faults? Answer: The common faults of the disconnector are: (1) The contact part is overheated. (2) Porcelain insulation damage and flashover discharge. (3) Refuse to pull and close. (4) Wrong pulling and closing. 2. The overheating of the contact part of the disconnector during operation is caused by ...

1. The high-voltage load switch can be used as a load switch, which has the effect of self-extinguishing arc, but its breaking volume is very small and very limited. 2. The high-voltage isolation switch generally cannot be used as a load switch. There is no arc extinguishing cover in the structure, and there are also disconnectors that can switch loads on and off, but the structure is different from load switches ...

1. The current value of the air switch is too low, and the load power is greater than the rated power of the air switch. 2. The load joint is not firm, and the joint is not compressed. 3. If there is a short circuit in the line, check whether the electrical plug is dry. 4. The line is aging and leaking, resulting in both the live wire and the neutral line.

(1) Before operation, check that the circuit breaker (switch) is in the opening position accordingly to prevent the isolation switch from being pulled and closed with load. (2) There is a locking device to prevent misoperation between the knife switch, the grounding knife switch and the switch, and the reverse operation must be carried out in order. If it is locked and cannot be operated, ...

Merit: Good stability: Linear power supply can provide stable output voltage and current, which is very suitable for circuits and equipment that require high power supply accuracy. Low noise: Linear power supplies have low noise, which is advantageous for applications that require a low-noise power supply. Responsiveness ...

First, the characteristics are different 1. Limit switch: The limit switch has the characteristics of small size, multiple functions, high precision, adjustable limit, strong versatility and easy maintenance, installation and adjustment. 2. Proximity switch: The proximity switch has the characteristics of a limit switch, and at the same time has the sensing performance.

Conversion conditions: The purpose of requiring dual power supplies is to complete the automatic and reliable conversion of dual power supplies under "specific" circumstances. This "specific condition" is the conversion premise of the dual power supply, or the conversion condition, which is the primary consideration for choosing the dual power supply. A. In the event of a power failure ...

1. Increase inductance and output capacitance filtering According to the formula of the switching power supply, the current fluctuation in the inductor is inversely proportional to the inductance value, and the output ripple is inversely proportional to the output capacitance value. Therefore, increasing the inductance and output capacitance can reduce ripple. In the same way, the output ripple is the same as the output ...

Pre-stroke - indicates the distance or angle at which the actuator on the limit switch must move before tripping the switch contact Operating Point - Indicates the position of the actuator when the switch contact is moved to the working position Release Point - Indicates the position of the actuator when the contact returns to its original state Differential - ...

1. Pull together the voltage transformer and lightning arrester under normal conditions. 2. Pull together the 220kV no-load bus. 3. The neutral point of the transformer when there is no ground fault in the latching grid. 4. Pull the bypass current that is closed by a switch or an isolated switch. 5. Outdoor vertical splitting triple isolation ...

Unmarked/Z: Inductive/inductive self-diagnosis C/CZ: Capacitive/Capacitive Self-Diagnosis N: NAMUR safety switch X: Analog F: Hall V: Reed type J: Threaded cylindrical B: Cylindrical Q: Angular cylindrical shape ...

1. It can isolate the power supply, with a significant disconnection point, and is mostly used for fixed high-voltage devices; 2. It has arc extinguishing equipment and a certain opening and closing rate, and can pass through the normal working current and the specified short-circuit circuit in the case of closing; 3. It is forbidden to connect and cut off the circuit with load, ...

1. When overhauling electrical equipment, provide an electrical interval and a visible disconnection point to ensure the personal safety of maintenance personnel. 2. The disconnector can not be operated with load: it cannot be operated with rated load or large load, and it cannot be divided or combined with load current and short circuit current.

1. Change the reference current of the feedback module Regulating the reference current is the most basic way to regulate the output current of a switching power supply, and it can usually be achieved by rotating a potentiometer or toggling a switch. Changing the reference current allows the magnitude of the feedback current to be compared with it, so as to control the switch ...

1. Wiring The design requirements of wiring are very strict in the design of switching power supplies, and they must be done well to pass the test. If the designer does not handle the wiring work in the early stage of design, there will be great safety hazards in the future electricity consumption. So here I recommend you to buy a switching electric ...

1 The contact is overheated Contact heat is mainly caused by the current flowing through the contact, and there is power loss between the contacts (such as contact resistance loss, arc energy loss). It is normal for the contacts to heat up, but severe heat (overheating) is a malfunction. The main ...
