1. The role is different The air switch is a kind of circuit breaker that protects the "object", which can protect the safety of the entire household wiring and electrical appliances and other items to prevent the wire from being burned due to overheating. The leakage protection switch is a kind of circuit breaker that protects "people", which can be cut in time when leakage.

Requirements for electrical barriers. Between A and B circuits, signal transmission is required, but because of the disparity between the power supply levels of the two circuits, one is hundreds of volts, and the other is only a few volts; Two very different power supply systems, unable to share the power supply; ...

1. Why does the maintenance function of the inverter operate when the clutch is connected to the load? When the load is connected with a clutch, at the moment of connection, the motor changes sharply from the no-load condition to the area with a large slip rate, and the large current flowing through causes the inverter to trip over the current and cannot work. ...

1. The aesthetic slab adopts frameless large buttons and fluorescent grid planning, giving people a comfortable texture experience. The large-pitch flat panel is simple and useful, and is available in four colours: Funky White, Champagne Gold, Starlight Silver and Midnight Black. 2 ...

(1) Optimize electrical equipment: when the motor is started, there is no large current impact, and the load of the transformer is reduced. (2) The energy-saving effect is obvious: it can reach 20%-45%. (3) Extend the life of the whole machine: it has the function of soft start, reducing the load ...

The control of the inverter is nothing more than the basic logic of starting, aborting, forward rotation, rotation, and speed regulation, which basically requires that the level condition is useful, not the rising margin is useful, so the use of button switches to control the inverter is generally required to use the button in the form of self-protection ...

Delixi CDI-EM60 series inverter is a high-performance inverter, with the following characteristics and use: Characteristic: 1. It has good stability and reliability to ensure the stability and safety of the system operation. 2. High degree, wide range of speed control, ...

1. Install AC reactor and DC reactor. When the inverter is used in the distribution transformer capacity is greater than 500kva, and the transformer capacity is greater than 10 times of the inverter capacity, an AC reactor is installed on the input side of the inverter. And when the output voltage of the distribution transformer is unbalanced and uneven in three phases ...

Inverter is a very widely used equipment in the modern factory, this is a new type of equipment, the price is very noble, and the price of inverter repair is also very expensive, so in the process of using inverter, pay attention to the use of inverter, on the one hand, inverter, delay inverter ...

Voltage vf and v difference: The two have different meanings, vf on the battery represents the feedback voltage, while v represents the capacity of the battery, which is the unit of measurement of voltage. Lithium battery is a kind of battery with lithium metal or lithium alloy as the positive/negative electrode data and the use of non-aqueous electrolyte solution. ...

1. According to the requirements of the device part and the needs of the maintenance function, reasonably select the motor maintainer model and its various maintenance action parameter settings; 2. According to the requirements of the product operation manual, the correct device should be connected correctly according to the use of each terminal, and the operating power supply should be connected to the control ...

Delixi solid state relay and Delixi communication touch device are more used products, so what are the advantages of solid state relay compared to communication touch device, how should we choose when we can choose? 1. First of all, solid...

The molded case circuit breaker tripper is divided into undervoltage tripper and shunt tripper. This article explains the wiring method of the circuit breaker with sub-excitation tripper. The shunt tripper is often used as an additional accessory for the user, it is a remotely operated circuit breaker disconnection device, installed in the molded case circuit breaker, when the shunt ...

1. Classification of switch operation organization At present, the switches we encounter are generally divided into many types, such as oil-rich type (old model, now you can't see it at all), oil-poor type (some user stations also have it), SF6, vacuum, GIS (combined electrical appliances) and so on. These are all about the arc extinguishing medium of the switch. ...

Typically, every electrical device or device is designed for a wide range of input voltages. Depending on the sensitivity, the operating scale of the device is constrained to a specific value, for example, some devices can tolerate ±10% of the additional voltage, while others can tolerate ±5% or less. ...

CDB1 miniature circuit breaker is a current-limiting high-breaking miniature circuit breaker with overload and short-circuit two-layer maintenance, which is suitable for communicating 50Hz, additional voltage 400V and below, and additional current 63A and below circuits.

1. If the fuse is burned out, please approve the load equipment as soon as possible, make repairs in time, and restore power; 2. If you use a fixed amount of fuse, please use a regular line, and do not match it at will, so as not to cause ...

When the VFD is viewed regularly, the power supply should be blocked, the operation of the VFD should be stopped, and the cover of the VFD should be removed. The first thing is to check the places that cannot be seen without downtime, or the places where it is difficult to find problems on a daily basis, as well as the inspection and adjustment of electrical characteristics. After blocking the VFD power supply, the main power ...

There are many soft problems in inverters, which are also one of the problems that generally exist in the operation of various types of inverters. So how can we reduce the occurrence of soft problems in inverters? This is a problem that all inverter manufacturers and users are very concerned about. More on that below. ...

1. Because there is leakage current in the inverter, in order to prevent electric shock, it is necessary for the inverter and the motor to be grounded. 2. Special grounding terminal for inverter grounding. To connect the grounding wire, use tinned crimp terminals. When tightening the screws, be careful not to break the screws. ...
