Contactor is the component of commonly used electric equipment in transducer control, basically use at switch amortize resistor to reach put through and switching circuit. Of contactor choose correct, affect the moving condition of the working quality of transducer and electric equipment directly, then affects the normal production of whole apparatus and safe stability. Handle the concerned issue of contactor seriously, the level of whole accident travel to raising transducer and product quality standard have real sense very much. What kind of contactor does transducer need after all? (1) can satisfy the insulation requirement of transducer, the security that enhances transducer is aimed at the insulation characteristic of transducer, contactor crust is used increase flame retardant nylon 66, isolation voltage is dc 1500v, 3500v of labour frequency compression. Eliminate safe hidden danger, the product can be installed directly go up in housing, enhance the security of transducer. (2) sheet is extremely straight because contactor is shedding the job on bus continuously,flow, switch an amortize resistor, need only one extremely. Reason design is sheet pole dc. According to 18.

The transducer of 5kw above power uses the characteristic of amortize circuit contactor, the voltaic norms of contactor should be 50a, 100a, 200a, 265, 400a, 600a, 800a. (The power cell of high temperature resistant, dustproof low-pressure transducer is 3) Igbt, want to produce quantity of heat when the job, to come loose heat wants to make up in transducer housing fan is used medicinal powder hot, this is reduced greatly with respect to the dustproof function that causes transducer interior. Installing the contactor in transducer interior namely is to be in temperature is higher, dust works below more environment. To solve these problems, the coil of contactor is used be able to bear or endure the enamel-insulated wire of 180 ℃ high temperature is circled make, the system that touch a head and magnetism system all should close inside housing. (4) satisfies the contactor in the control voltage transducer of all sorts of norms, control voltage cent is dc and communication two kinds of genre. Dc control is given priority to with Dc24v, prime cause is they think dc 24v comes loose sirocco fan performance is steadier, reason contactor also uses dc 24v, can mix fan is common power source of a switch. Communication control is given priority to with Ac220v and 380v. Communication 220v needs to pass control transformer, although raised the dependability of contactor, but also raised cost, and communication 380v need not control transformer. Can saying about controlling voltage is opinions differ from each other, shed 24v continuously, ac220v and 380v are possible. (5) installation means is accorded with the standard of transducer is at present current the brand that three-phase communication contactor uses on transducer is very much, have an appearance that suits an industry and installation measure harder, but bolt and calipers can consider when the design means of two kinds of installation. The manufacturer home of contactor of sheet pole dc is not much, and product installation dimension is more unified. The appearance when reason is being designed and installation dimension and existing product keep consistent, transducer manufacturer need not any altering can use directly. CNC Milling CNC Machining
