Summary: ATSE has been applied more and more extensively in all sorts of fundamental situations that use phone, author discovery, when great majority stylist is choosing ATSE, pay close attention to its merely rated electric current and progression, and characteristic to deciding ATSE works crucial index: Changeover condition, utilization category and changeover time did not add an attention, reason close-up this article consults with offerring.

Keyword: Power supply of power source of AISE key switch

, a few fundamental conditions about ATSE

1.ATSE is decision power source whether the crucial switch that supplies normally. Normative requirement designs power supply of two power source to main negative charge, and the dependability that double power source supplies a system, basically depend on the dependability of ATSE, the breakdown loss of ATSE is more than the breakdown loss of other electric equipment, dependability is the main basis that chooses ATSE.

2.ATSE is the most complex switch in low-pressure switch, it is true intelligence switch, a complete ATSE includes controller of switch noumenon ＋ , among them the electric character of ATSE of switch noumenon decision, controller decides the changeover of ATSE is characteristic. Because of utility different, often noumenon of a kind of switch can combine different controller, realize different changeover character. Controller is the cerebra of ATSE, but be ignored generally at present, this is our country ATSE from the design, create the question with the biggest application.

3.ATSE has not carried out CCC attestation, the basis that can prove the product accords with ATSE to ask exclusively is CQC attestation, at present home has brand of hundreds of ATSE, but the material that publishs according to center of Chinese certificate of quality, only a few 50 pass CQC attestation, still have the product that experiments without any type in great quantities using, bury next very big safe hidden trouble. No matter be the ATSE of what brand, indispensible undertake CQC attestation ability is sold quite and be used.

4.ATSE has had product level (GB/14048.11) with design standard (see " civilian compasses " pertinent clause) , but still check and accept a standard without what unite, because be restricted by spot condition, actual occasion is falling without laden state, cut off commonly used power source, whether is examination ATSE changed reserve power source, receive a commonly used power source next, examination ATSE is automatic restoration. Some projects do not have any checking and accept even, cannot discover the product that has quality problem, leave very big safe hidden trouble, designing only, purchase level to be controlled strictly.

The stylist of the majority is designing 5. when ATSE, often consider rated electric current and progression only, and to deciding ATSE core function " reliable below power source breakdown changeover " parameter: "Changeover condition, utilization category and changeover time " did not grant generally to take seriously, and the difference place that these 3 important parameter also are different brand. What the disorder that supplies because of ATSE market and model tag is non-standard, tag model, electric current, progression merely 3 index, do not have almost to ATSE " control force " , bring about finally use improper product, leave potential hidden danger.
