CB level and PC level ATS dual power switch 1. The difference between those who have the following two different mechanical design concepts CB-level dual power supply is composed by the circuit breaker, and the circuit breaker is to have any break arc requires its machinery should fast . Thus the existence of a circuit breaker tripping mechanism of the slider, then buckle the problem; while PC-class product does not exist in the aspects of reliability .PC grade products is much higher than 2. CB-level product does not carry the short-circuit withstand current circuit breakers, When the contact pressure is small supply short circuit occurs when the contact is opened denounced produce limiting role, thus breaking the short-circuit current; and PC-class ATS shall be subjected to more than 20Ie overload current and contact pressure can not easily be denounced open, thus contacts. can not easily be welded. This feature is particularly important for fire power system 3. dual power supply in the presence of the conversion process issues superimposed PC level ATS fully consider this factor .PC level ATS dual power electrical clearance, creepage distances 180%, 150% (standard). Thus ATS PC level security is better. Different angles 4. Select the contact material dual power circuit breakers often choose silver tungsten, silver, tungsten carbide material pairing, which is conducive to breaking the arc. But easily oxidized materials such contacts, contacts backup long exposed, its performance is easy to form an oxide conductive obstacle, get rid of difficult, but when put to use an alternate contact, the contact temperature switch easily lead to increased burning or explosion; The PC-level ATS fully consider the consequences caused by oxidation of the contact material, especially in Japan, Kyoritsu of ATS its junction silicon alloy, highly resistant to burning, and when the switch is running, every contact can clean dust from the sliding contacts and oxidation, which greatly improves the life of DPT ATS dual power models, reducing the risk of isolation dual power switch normal operating conditions and installation conditions (1) Ambient air temperature: the upper limit of not more than + 40 ℃ dual power, under limit of not less than -5 ℃, the average of 24 hours does not exceed 35 ℃ (2) elevation: the installation site altitude does not exceed 2000M. (3) atmospheric conditions: air relative humidity at the installation site + 40 ℃ maximum temperature does not exceed 50%, at a lower temperature allows a higher relative humidity DZ47 dual power switch, the wettest month of the monthly average Minimum temperature does not exceed + 25 ℃, (4) Pollution degree: meet three GB / T14048.1 regulations. (5) Installation Category: Surnames electrical switches mounted in line with Class Ⅲ category GB / 14048.1 requirements. Installation category Ⅱ switching controller comply with class GB / 14048.1 requirements. (6) Installation conditions: the conversion of electrical switches and controllers can be mounted vertically or horizontally installed in a dedicated control cabinet or distribution cabinet. (7) Protection rating: Surnames electrical switches mounted in line with IP20 grade category GB4208 requirements. Conversion controller installation category IP30 level of compliance with the provisions of GB4208. (8) Control circuit: Rated control circuit voltage of AC 220V / 230V / 50HZ, mining circuit voltage (UC) should switch controller operating voltage US agreed Han Kwang dual power switch, dual power switching control appliances when the following When the situation, switching controller will issue a conversion instructions. (A) break any one phase or loss of pressure; (b) Brown: between 180V-230V can be set arbitrarily. (C) overpressure: between 220V-250V can be set arbitrarily. If the user requires no special orders and instructions, the factory rated normal operating voltage of -220V, switching voltage is set to: -180V, overvoltage: -250V shell intelligent dual power switch _ _ dual power only by Shanghai Thai Industries Thai Industrial Co., Ltd.
