Tianyi switch - the difference between high-voltage load switch and high-voltage circuit breaker

1. Through the isolation switch, it plays a good insulating role, so that the whole circuit can be safe and secure, and the maintenance personnel or staff also have enough ability to repair the circuit. 2. At the same time, the low-voltage isolation switch can also change the operation mode of the circuit, which is used in the power plant or gas plant.

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, ...

The so-called PNP and NPN proximity switches are for the type of DC three-wire proximity switch output transistor, and even though many proximity switch output stages use MOS transistors, they are still called the same. Differences: PNP type proximity switch: The type of proximity switch output transistor is P...

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. It can isolate the power supply, have obvious disconnection points, and is mostly used for fixed high-voltage equipment. 2. It has an arc extinguishing device and a certain opening and closing speed, and can pass the normal working current and the specified short-circuit circuit in the closing state. 3. It is strictly forbidden to turn on and off the circuit with load.

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 ...

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 ...

Generation and transmission of electromagnetic interference There are two ways of electromagnetic interference transmission: one is conducted transmission and the other is radiated transmission. Conducted transmission is a complete circuit connection between the interference source and the sensitive equipment, and the interference signal is transmitted to the receiver along the connected circuit.

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.

First, the principle is different 1. Class Cb automatic switch is an electronic product that converts one or more load circuits from one power source to another 2. PC-level automatic transfer switchgear is an electrical appliance that converts one or several load circuits from one power supply to another. ...

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.

1. First open all the packages of the newly bought limit switch, confirm that the parts in each package are not missing and complete, and then discharge all the parts in turn. 2. Then open the body part of the limit switch, as long as you loosen the screws with a screwdriver.

1) Clean the dust on the surface of the porcelain, check whether the surface of the porcelain is glazed or damaged, whether there are cracks and flashover marks, and whether the iron and porcelain joints of the insulator are firm. If the damage is severe, it should be replaced; 2) Wipe the oil stains on the blades, contacts or fingers with gasoline and check the contact ...

1. Install the dual power transfer switch with the power supply to ensure the correct access of the power supply. 2. Adjust the handle of the dual power transfer switch to the "automatic" position, so that the power supply will automatically detect the state of the other power supply, when one of the power supplies fails, the other power supply will ...

1) Ambient air temperature: The upper limit of ambient air temperature is +40°C, the lower limit of ambient air temperature is -5°C, and the average value of ambient air temperature for 24h does not exceed +35°C 2) Altitude: The altitude of the installation site does not exceed 2000m. 3) Atmospheric conditions: Atmospheric relative humidity in the surrounding air ...

1. Provide an electrical interval and a visible disconnection point during electrical equipment maintenance to ensure the personal safety of maintenance personnel [3] . 2. The disconnector can not be operated with load: it cannot be operated with rated load or large load, and it cannot be divided and combined with load current and ...

1. Protection The most important role of the limit switch must be its protection effect, the limit switch is also known as the travel limit switch, which is mainly used to control the stroke of mechanical equipment and limit protection. In practice, the travel limit switch is installed in a pre-arranged position, and the travel limit switch is installed in a pre-arranged position.

1. Common air switch models in the family Common family models: DZ series, C16, C32. C40, C80, C100, C120 and other products, of which C represents the starting current, such as: C32 means that the starting current is 32A, which can drive a 6500 watt water heater, C40 ...

The socket, lamp head, kitchen, bathroom, refrigerator, air conditioner of each route should be put out separately, and each route should have a separate air switch, high-power rooms, such as kitchens and bathrooms, the line of more than 4 square millimeters should reach 20A, and the general lamp head line should only be 16A, and each line ...
