The main features of VTeam X42 series limit switches

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) Green (HG, GL) What it means: stands for Safety, Normal, Readiness (i.e., an indication under safe operating conditions or the readiness of a mechanical device to start). Function: It is often used to indicate the state of equipment ready to start, all auxiliary components are in a state of preparation for operation, and various parts ...

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.

(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 ...

How to use the indicator color correctly? 1. The indicator light (also known as the signal light) is mainly used to attract the attention of the operator or instruct the operator to carry out a certain operation in the way of bright indication, and as an indication that a certain state or instruction is being executed or has been executed. 2. General ...

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. 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. 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.

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. 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 ...

1. Frame circuit breaker (universal type) - ACB: Rated current: In principle, frame circuit breakers are required for rated currents above 630A, and molded case circuit breakers are generally below 630A. It can be seen that the rated current of the frame circuit breaker is much larger, generally 630A-6300A. In addition in segments can ...

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. 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.

(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, ...

An overview of limit switches Limit switch is a kind of mechanical orientation and electronic control interface, the mechanical action into electrical signals, is suitable for industrial environment of a common electromechanical and electrical components, through the contact way to detect the object, the existence and so on. It is possible to control the device's ...

1. Use less plastic switches The switch is composed of a panel, a current carrier, a nozzle and a base, etc., and a good switch is mostly made of stainless steel inlay, which is safe and anti-electric shock. On the contrary, most of the inferior switches are made of plastic, although they are insulated, they are prone to leakage and flammability, and potential safety hazards will occur. 2 ...

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) 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 ...

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.

First, the characteristics of the load switch A load switch is a switchgear between a circuit breaker and an isolation switch. It has a simple arc extinguishing device, which can cut off the rated load current and a certain overload current, but cannot cut off the short-circuit current Second, the classification of load switches According to the operating voltage ...
