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

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 ...

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 ...

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 ...

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. ...

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 ...

LW42 series LW42 series cam switch and safety switch are another series of high-quality products announced by Shanghai Tianyi Electric Appliance Co., Ltd. to meet customer needs. Device function: personal safety is paramount, LW42 series cam switch and safety switch unique terminal plan ...

(1) Eddy current proximity switch This type of switch is sometimes called an inductive proximity switch. It is the use of conductive objects when they are close to the proximity switch to produce eddy currents inside the object. This eddy current reacts to the proximity switch, causing the internal circuit parameters of the switch to change, so as to identify the presence or absence of ...

First, the repair method The maintenance of a switching power supply can be carried out in two stages (1) When the power is cut off, it is "Look, Listen, Listen, Measure" Look: Open the power box, check whether the wire is disconnected, look inside the power supply, and find that the PCB substrate of the power supply is scorched or the components are cracked.

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...

1. Differences in appearance Although these two types of switches seem to be very familiar, but there are still differences, half of the leakage protection switch is the same as the air switch, and the other half is not, it is equipped with a test jump button and a recovery button, which are not available in the air switch. 2 ...

1. The circuit breaker is equipped with an arc extinguishing device, so the circuit breaker can be operated with load, but it cannot operate the current of the load. The disconnector does not have an arc extinguishing device, and it can operate places where the load current is less than 5A, but it is generally not suitable for operation with load. 2. And the circuit breaker ...

(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, ...

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. 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. 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. 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 ...
