What are the advantages of Tianyi switch - limit switch?

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. 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. Buttons 1. Red Operation in hazardous situations. It is often used for emergency stops Stop and break. It is often used to stop all machines, stop one or more motors, stop a certain part of a piece of equipment, make the electrical components lose power, and have a stop function reset button. ...

The scope of use of the travel switch (limit switch). The range of use of travel switches (limit switches) is very wide, so what is the effect of travel switches (limit switches)? The position switch (limit switch) refers to the maintenance of the micro switch from external forces, oil, water, gas, ...

1. Determine the type and protection form of the circuit breaker according to the requirements of the line for protection - determine the selection of frame type, device type or current limiting type. 2. The rated voltage UN of the circuit breaker should be equal to or greater than the rated voltage of the protected line. 3. The rated voltage of the circuit breaker undervoltage tripper ...

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 ...

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. Repeated short-circuit test ◆ Test instructions The output of the module is short-circuited in various input and output states, the module should be able to achieve protection or retraction, repeated short-circuits, and after troubleshooting, the module should be able to automatically resume normal operation. ◆ Test Method a ...

Uses: X42 series limit switches can be widely used in various types of mechanical equipment, automatic assembly lines and other light and medium load occasions, can detect the object action state, such as presence and absence, movement position, end of stroke, etc. Overview: The switch is mainly composed of switch operating parts, ...

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.

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.

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 ...

daily life There are many aspects of the use of limit switches, and it is found in many electrical appliances. So what effect can such a simple switch have? It is first and foremost a chain maintenance effect. The most common example is its use in washing machines and tape recorders (video recorders). ...

The dual-power automatic transfer switch is mainly used in the emergency power supply system, which automatically switches the load circuit from one power supply to another (standby) power supply switching appliance to ensure the continuous and reliable operation of important loads. Therefore, the dual-power automatic transfer switch is often used in important places of electricity consumption.

1) Voltage Setting: Turn on the DC switch, adjust the voltage knob to adjust the voltage reading to the desired operating power connection. If you need to lower the voltage, turn the potentiometer slowly so that the drip rate of the voltmeter is compatible with the speed of the manual adjustment knob. 2) Constant Current Setting: Connect ...

1. When closing, first of all, attention should be paid to check that the circuit breaker that can be connected to the dual-power automatic transfer switch is indeed in the opening position, and then quickly operate the risk isolation switch to close it (whether the enterprise adopts manual management agency or leveraged financial institution personnel operation), but ...

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 ...

1. In addition to the short-circuit protection function of the fuse, the air switch can also realize the overload protection of the circuit. 2. The fuse is a one-time protection device, which must be replaced once it is blown and is very troublesome, so its reusability rate cannot be compared with the air switch. ...

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 ...
