Use electric equipment of automatic transfer switch correctly

From;    Author:Stand originally
  summary: The article introduced electric equipment of automatic transfer switch (the development course of ATSE) , elaborated electric equipment of automatic transfer switch (the definition of ATSE) , classification, executive standard and point of design type selecting.

Keyword: ATSE of electric equipment of automatic transfer switch

In low-pressure power supply system, a few main negative charge if: The power supply place such as building of fire control, hospital, bazaar, bank, high level, need two-way or multichannel power supply, finish the device of two-way power source or task of switch of multichannel power source or product, call system of power source switch.

As in last few years technical progress is mixed development, appeared in system of power source switch a kind of new-style product -- electric equipment of automatic transfer switch (ATSE) , it by 1 (or a few) the electric equipment composition with transfer switch electric equipment and indispensible other, use at monitoring power source circuit, and will 1 or a few laden circuit is changed automatically to from a power source additional a power source? It is special the new-style product that changes at power source. Can say electric equipment of automatic transfer switch (ATSE) is representing system of power source switch kind the direction that the product develops. Below introduce system of power source switch simply kind the course that the product develops.

1, system of power source switch kind the product develops course

The cent of relevant product cardinal principle of system of power source switch is 3 kinds: Contactor kind, air breaker kind, power source is automatic transfer switch electric equipment (ATSE) kind, among them automatic transfer switch divides power source to be air switch and bear switch-disconnector for switch part again two kinds.

1.1 contactor kind

System of switch of this kind of power source is switch part with contactor, switch function uses auxiliary relay or logistic control module comprises loop 2 times to finish control function, it is the product that be not mark commonly, defect is advocate loop contactor job needs loop 2 times long-term electrify, easy generation temperature rise the breakdown such as burn down of felt of calorific, contact, coil. Because of dispute mark product, its comprise yuan of parts of an apparatus more, product quality suffers yuan of parts of an apparatus, workmanship to restrict, fault rate is higher, already was replaced by new product gradually now.

1.2 air breaker kind

System of switch of this kind of power source is switch part with breaker of model carapace air, switch function is finished with ATS automation unit, have machinery and electric chain, the function is perfect, comprise yuan of parts of an apparatus less, installation is convenient, do not have circuit 2 times, but the price is higher, in ark of general park distribution, use in computation electric current is bigger (630A above) place. For Shi Naide on behalf of the product the ATS product of electric company is mixed product of SE of / of ABB company DPT.
