Tianyi switch - the role of low-voltage isolation switch

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 ...

Different designs, front panels and dedicated switches ensure optimum sensitivity to meet the requirements. Q1: P switch and T switch have ...

Q1: What is the difference between P switch and T switch? A: P switch is a load isolation switch, mainly used for the opening and isolation of the main circuit load, only 3P and 3+N, can add auxiliary contacts; The T-switch is a multi-function switch with a wide variety of contact sequences, modular contact units, which can ...

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. 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 ...

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. 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 ...

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. 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.

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 ...

Ambient air temperature: upper ambient air temperature +40°C; The lower limit of ambient air temperature is -5°C; The average temperature of the ambient air for 24 hours does not exceed +35 ° C. Altitude: The altitude of the installation site does not exceed 2000m. Atmospheric conditions: Atmospheric relative humidity at ambient air temperature of +4 ...

1. Altitude: 2000m and below; 2. Ambient temperature: -25°C-+40°C; 3. Relative humidity: the daily average value is not more than 95%, and the monthly average value is not more than 90%; 4. Places without conductive dust, corrosive gases and water vapors; 5. No fire ...

1. First of all, it is necessary to select the appropriate input voltage specification; 2. Choose the right power. In order to extend the service life of the power supply, it is necessary to select an additional type with 30% of the rated output power. 3. Consider the load characteristics. The load added is a motor, bulb or capacitive load, and the current at start-up ...

TPB1 series pushbutton switch is designed by VTeam's senior R&D technical team, which is suitable for a variety of industries and various occasions. TPB1 series pushbutton switches have a complete range of colors, rich colors, economic and durable, easy installation and superior performance. Automated production, testing, and quality control are more stringent, and the products are ...

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 ...

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. 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 ...

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, ...

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.

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 ...
