In fact, there is no fixed price for the control cabinet in the market. Because the control cabinet in Hunan Province is only a general term for a complete set of equipment control cabinets composed of controllers, the internal electrical components and functions are not fixed. There are many kinds of control cabinets in Hunan Province, including touch screen control cabinet, electrical equipment control cabinet, variable frequency control cabinet, fire control cabinet, explosion-proof control cabinet, high pressure control cabinet, centrifugal water pump control cabinet, etc. A wide variety of non-standard control cabinets can be customized according to the application. The control cabinet has different design schemes for different main purposes, so the relevant spare parts used internally are also different. There are many factors that endanger the price difference of the control cabinet, and it is normal to have a large price difference.

For example, the variable frequency control cabinet in Hunan Province is different according to the power of the control motor, the number of pumps and the brand of electrical components. Frequency conversion cabinet more common output power is divided into 3kW, 4kW, 5.5kW, 7.5kW, 11kW, 15kW, 18.5kW and so on. The price of the control cabinet also varies from several thousand yuan to tens of thousands of yuan. The price is determined by the total number of control stations, the configuration of electrical components and the functional provisions. From the perspective of industry development prospects, the elements that harm the price difference of the control cabinet are mainly manifested in the following aspects.

The control cabinet has a wide range of applications. Different industries have different control requirements, different control plans, different program modules, different spare parts and electrical components, and of course different prices.

Key controller brand model specifications are not the same, the price varies greatly. There are many brands in the world. There are many models and specifications in various brands, and the price of each model is different. Therefore, the price of the control cabinet has a certain trend to promote development.

Different types of parts brands. A control cabinet has hundreds of spare parts, each of which has a difference in brand, model, specification and function. The choice and price of each part are different.

Demand for electricity is not the same, the price is not the same. The control point is fully functional and can meet the control regulations. Controlling the total number of output and input points requires a certain loss of functionality. The more I/O points, the more functional losses and, of course, the greater the efficiency required. The greater the demand for electricity, the higher the price

The overall strength of the control cabinet manufacturer has a certain impact on the price. The professionalism of a company can be expressed in the production of solutions, the installation and commissioning of new products and the attitude of the service project process. Product quality and quality are good, so good goods value high price.

The control cabinet is a kind of automatic control system machinery and equipment, which is widely used in industrial production, diagnosis and treatment, daily life water supply and drainage, wastewater treatment, road transportation, metallurgical industry, chemical plant, agriculture and animal husbandry, irrigation, mechanical equipment and other fields. The control cabinet has strong stability, high performance and strong anti-interference. Despite this advantage, it is very easy to affect the control cabinet if it is affected by the harsh environment or operational errors in use, resulting in operational errors or uncontrollable machinery and equipment. Therefore, in order to ensure the stability and service life of the machine, some problems should be paid attention to when using the control cabinet. Now let's take a look at the five elements that affect the use of the control cabinet.

Five factors affecting the use of PL power energy control cabinet

Office environment and temperature level, the general requirements in 0~55 degrees above. If it is higher than this temperature range, you need to pay attention to the refrigeration control cabinet. You can rely on the louver curtains in the cabinet for air circulation, and you can also use a fan to ventilate the room in the cabinet. If not, it is necessary to desuperheat all control cabinets. When the temperature is less than 0 ℃, a small and medium-sized electric heater shall be installed in the cabinet to heat the temperature to the specified temperature range.

Ensure that the humidity of the air occupied by the control cabinet is less than 85% and there is no condensation. At the level of the air index, dust, cotton, corrosive gases and flammable gases should be avoided. It shall be installed in the control cabinet with good sealing performance.

When using the control cabinet, prevent direct sunlight or rain. If water enters the cabinet, it will affect the normal operation of the components. If it is more serious, it will also lead to a short circuit fault of the power circuit, machinery and equipment, resulting in an electric shock accident and endangering the person.

If the control cabinet is subjected to constant or frequent vibration and impact, it may cause loose parts in the cabinet, poor contact and mechanical failure. Therefore, the control cabinet installation should avoid strong vibration source and impact source. If you can not avoid the shock shock, you can use anti-seismic silicone ring shock.

When the control cabinet is applied, the indoor ventilation in the cabinet is guaranteed to be smooth, and the installation method of each component is effective, which is conducive to inspection and maintenance in case of abnormality in the future. At the same time pay attention to the transformer, frequency converter,. In addition, it is necessary to expand the embedded indoor space for the future system to avoid mutual influence.
