At present, as the low-voltage electrical appliance industry continues to advance, but also because of the rise of “CPS fever†in the industry, the entire industry has evolved from a simple focus on hardware to a focus since it focused on the characteristics of the product and began to focus on applications and solutions. Electrical environmental protection and intelligent design. Over the years through the hard work of all Rockefeller employees, but also with the help of colleagues in various design institutes, complete sets of plants, and users, Rockefeller has also integrated the traditional KB0 series of control and protection switches into functional modules. The transformation of the KB2 series of control and protection switches with high levels of protection and easy installation. #Industrial Solutions# Hospitals
Various hospitals, especially modern ones, provide uninterrupted power supply for advanced medical equipment and important treatments to ensure that no disruption occurs. The supply of two-way power supplies or emergency power supplies is related to the patient’s life and death. Our highly reliable dual power switches for hospitals ensure 24/7 power supply and reduce energy consumption without compromising patient care.
Coal Mines Rockefeller's products are highly reliable, and can provide overall product solutions, reduce downtime and other emergencies, protect related equipment, improve safety and productivity, reduce costs, and achieve sustainable development. Construction Along with the raging domestic construction, a large number of buildings have emerged throughout the country. Lighting, living water pumps, sewage pumps, elevators and many other electrical appliances in various buildings have imposed higher requirements on the reliable supply of electrical energy. Due to its high reliability, Rockefeller products reduce the number of equipment failures and maintenance costs. At the same time, efficient and flexible after-sales service acts as your backup staff, lifting your worries. Railways Rockefeller's series of products are highly reliable because of its high reliability, the high availability of power supply to ensure the normal operation of the electric locomotive, the reliable supply of signal power to ensure the safe operation of the train. The features of the air defense civil defense project determine its demand for the power system. At the same time, the reliability of the power supply is very high. Our dual power switches ensure the power supply, and the two-speed fan ensures clean air. Among them, the fire-fighting type products have realized that the product will issue an alarm signal under the overload condition and continue to operate; in the case of a short circuit, an alarm signal will be issued at the same time as the trip, and it is even more perfect. Plants Today, with increasing degree of automation, the plant's motor control center has very stringent requirements for continuous operation performance, and short-term power outages will bring huge losses. It is imperative to improve the reliability of the control system by remotely controlling the motor to achieve unattended operation and improve energy efficiency. Other applicable places: It can also be applied to chemical industry, schools, ports, hotels, ships, textiles, metallurgy, petrochemical and other occasions. It is an ideal product to replace the current electromagnetic starter, protection type and combined starter. Application Monitor the crusher failure of the crusher by detecting the motor current. Operating conditions â– Power: 400V, 90kW.â– In:185A.
â– Run level S1.
â– Control circuit voltage: AC 230V. Products Used KB2-N Reversible Functions â– Short-circuit protection with a protection capacity of 70 kA at 400V.
â– Electronic thermal overload protection with an adjustable range of 4x.
â– Check the crusher failure of the crusher by sensing overcurrent. In order to use the "over-torque or blocking" function, the following parameters must be entered:
â–¡ Tripping: Answer Yes/No to enable or disable this feature â–¡ Pre-trip time: The duration of the trip that occurs when the current is below the trip threshold (adjustable between 1 and 30 s).
â–¡ Trip threshold: The percentage of the load current relative to the set current. If the ratio stays below this threshold for the duration specified in the previous parameter, the product will trip (can be adjusted from 100% to 800%).
