Tianyi switch - the principle and main purpose of transfer switch

1. The air switch is an important electrical appliance in the low-voltage distribution network and power drive system, which integrates control and a variety of protection functions. In addition to completing contact and breaking circuits, it can also generate short circuits to circuits or electrical equipment. Protection against severe overloads and undervoltages, etc.

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.

Internal accessories Auxiliary contact: The auxiliary contact is the contact mechanically linked by the main circuit of the circuit breaker, which is mainly used for the display of the circuit breaker opening and closing status, and is connected to the control circuit of the circuit breaker through the opening and closing of the circuit breaker to control or interlock its related electrical appliances. For example, to ...

1. If it is installed on metal, a certain space must be ensured to avoid interference between the proximity switch and the metal other than the detection object, resulting in failure. The metal parallel to the sensing surface must be 3 times the sensing distance from the sensing surface. The metal around the shaft of the proximity switch must be outside the cylinder, close to ...

First, the reason for the fault of the induction circuit of the switch button indicator 1. Aging of circuit board: The circuit board of the switch button indicator induction circuit board may be aged if it has been used for too long, resulting in leakage in the circuit, and then the induction failure of the indicator light. 2. Sense ...

First, first place the dual power supply on the adjustment table, and the phase wire and the neutral wire (neutral line) are docked in place, and can not be connected wrongly. Second, after the line is connected, it is necessary to check the installed line, and then turn on the main switch of the debugging station to turn on the common and standby working power supply. Three, when the double ...

1. The design is usually simple and straightforward 2. Works well in almost any industrial environment 3. It has high accuracy and repeatability 4. Low-power devices 5. High inductance load can be switched 6. Used to switch multiple loads 7. Simple installation ...

performance 1. Adopt double-row composite contacts, cross-connected mechanisms, micro-motor pre-energy storage and micro-electronic control technology, basically achieve zero arcing (no arc extinguishing cover); 2. Adopt reliable mechanical interlocking and electrical interlocking technology; 3. Adopt zero-crossing technology; 4、 ...

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.

In the design of switching power supply, the physical design of the PCB board must be proper, otherwise it may cause excessive electromagnetic interference and lead to unstable power supply. 1. The design process from the schematic diagram to the PCB should be rigorous and perfect: the establishment of component parameters ...

(1) The cost of linear power supply is higher than that of switching power supply at a certain output power point. Therefore, with the development and innovation of power electronics technology, the switching power supply technology continues to break through and innovate.

1. What is the reason why the empty trip cannot be pushed? 1. If the air opening itself is faulty or damaged, the air opening should be replaced with a new one. 2. If the line is caused by a short circuit, the line should be found first, and then reconnected.

What are the uses of air switches 1. The air switch is an important electrical appliance in the low-voltage distribution network and power drive system, which integrates control and a variety of protection functions. In addition to completing contact and breaking circuits, it can also generate short circuits to circuits or electrical equipment. Severe...

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 ...

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.

The load switch and combination electrical appliances are mainly composed of frames, isolation switches (the current limiting fuse of the combination is on the isolation switch), vacuum switch tubes, grounding switches, spring operating mechanisms, etc. The product has compact structure, small size, long life, strong closing and breaking ability, and simple operation and maintenance.

1. Check the key points: 1) Whether the voltage at point B is 310V. 2) Whether the 15V voltage is normal. 3) Whether the voltage at point C is greater than 14V. 4) Whether the SS terminal of (8) pin IC6 is higher than 10V, whether the SD terminal of pin (10) is lower than 0.6V, and whether there is a square wave transmission at pin 13 and pin 14 ...

1. No output, the fuse is normal This phenomenon indicates that the switching power supply is not working or has entered the protection state. First of all, it is necessary to measure whether the starting pin of the power control chip has a starting voltage, if there is no starting voltage or the starting voltage is too low, it is necessary to check whether the starting resistance and the external components of the starting pin are ...

1. After opening, establish a reliable insulation gap to separate the equipment or line that needs to be overhauled from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment. 2. According to the operation needs, change the line. 3. It can be used to divide and combine small currents in the line, ...

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 ...
