Nantong sea as laser cutting the opportunity to choose what kind of low-voltage electrical appliances

Nantong sea as laser cutting the opportunity to choose which low voltage apparatus, laser cutting machine low-voltage refers to the communication and dc 500 v and 1200 v and below the following circuit on and off, control, protection, detection, transformation and adjustment of components or equipment. Low voltage apparatus according to the different conditions, cutting machine have different classified method. Cutting machine the development of low voltage apparatus, depends on the development of the national economy and the needs of the development of modern industrial automation, and new technologies, new processes and new materials research and application, at present, is moving toward the high performance, high reliability, miniaturization, d/a, modular, combination and parts generalization in the direction of development. According to cutting machine electrical components in the system classification according to electrical appliances in the system can be divided into two categories, low-voltage distribution control appliances and low-voltage electrical appliances. ( 1) Low-voltage distribution electrical appliances are mainly used in low voltage power grid or power plant, the protection circuit and equipment and appliances on and off, switching power supply, or load, such as fuse, knife switch, etc. ( 2) Low voltage control electric equipment is mainly used in low voltage electric drive system, the running of motor control, adjustment, test and protection of electric equipment, such as contactors, relays, command buttons, etc. According to the principle of laser cutting machine electric action classification according to the principle of electrical activity can be divided into two categories, manual electric and automatic. ( 1) Manual appliances is made by artificial operation instructions, such as the knife switch, button, etc. ( 2) Automatic appliances is completed by electromagnetic suction make electrical automatic motion commands, such as contactor, relay, solenoid valve, etc. According to the role of electric equipment in the system classification according to the role of the electric equipment in the system can be divided into the control electronics, testing appliances, computing appliances, protection of electrical appliances and execution. ( 1) Control the electric equipment is used in a variety of control circuit and control system of electric equipment, such as contactor, relay, etc. ( 2) Testing appliances is used in the system feedback signals and signal of various electrical appliances, such as electromagnetic sensors, travel switch, etc. ( 3) Appliances is applied to the transformed signals according to the need of electrical appliances, such as intermediate relay.
