ANSI C78.180-2003 (R2016) Page i 2016 National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by The American National Standards Institute, Inc. (ANSI) that the requirements

13、for due process, consensus, and other criteria for approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review

14、, substantial agreement has been reached by directly, and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resol

15、ution. The existence of an American National Standard does not in any respect preclude anyone, whether s/he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. It is intended as a guide to aid the m

16、anufacturer, the consumer, and the general public. The American National Standards Institute, Inc., does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an

It does not include starters that are an integral part of a lamp or manually operated switches that may be used for lamp starting. 2 Normative

31、ed typesDimensional and Electrical Characteristics ANSI C82.1-1997 Line frequency fluorescent lamp ballasts UL 542 Standard for Lampholders, Starters, and Starter Holders for Fluorescent Lamps 3 Definitions 3.1 General Starters are devices which initially connect the cathodes, usually in series, of

32、fluorescent or similar discharge lamps directly across the ballast-supply circuit so as to provide cathode preheating. When the starter contacts open, the voltage transientdue to interrupting the current through the ballastis applied across the lamp to establish an arc. Starters also include a capac

33、itor for the suppression of radio interference during lamp starting and lamp operation. They may also include a circuit-opening device, arranged to disconnect the preheat circuit if the lamp fails to light normally. 3.2 Glow Switch Starters This type has normally open contacts, in a gaseous atmosphe

34、re. One or both is a bimetal strip(s). On starting, the full supply voltage is applied across the open contacts, producing a glow discharge. Heat from the discharge actuates the bimetal strip(s), the contacts close (extinguishing the glow), and cathode preheating begins. When the bimetal strip(s) co

35、ol sufficiently, the contacts open. The resulting interruption of the current through the ballast produces a transient which usually starts the lamp. Should the lamp fail to start, the above process repeats. 3.3 Thermal Starters This type has normally closed contacts, one or both of which is a bimet

36、al strip(s). Also, it has a heating coil in series with the ballast and lamp cathodes. When the supply voltage is first applied to the circuit, cathode preheating begins immediately. The heating coil actuates the bimetal strip(s), causing the normally closed contacts to open after an adequate prehea

37、t time, and the lamp starts. During lamp operation, a small amount of energy is consumed by thermal startersby a heating coil which keeps the contacts from reclosing. This type of starter is no longer commonly available and is not covered in this standard. ANSI C78.180-2003 (R2016) Page 2 2016 Natio

38、nal Electrical Manufacturers Association 4 Starter Identification 4.1 Marking Starters shall be marked to indicate their type according to 4.2 and with the rating of the lamps with which they are intended to be used. Other markings may be required by UL 542. 4.2 Types of Starters The following type

39、descriptions are given for starters, together with markings that shall appear on the starter enclosures 4.2.1 Simple Glow Switch This device contains no lockout element. There is no required marking. 4.2.2 LockoutManual Reset Glow Switch This device automatically removes the lamp from the circuit el

40、ectrically when the lamp becomes deactivated. The circuit is restored manually. Starter enclosures shall be marked “Manual Reset.” 4.2.3 LockoutAutomatic Reset Glow Switch This device automatically removes the lamp from the circuit electrically when the lamp becomes deactivated and automatically res

41、ets when the lamp circuit is interrupted. Starter enclosures shall be marked “Automatic (or Auto) Reset.” 4.3 Nomenclature See table 1 for type designations. Some types of starters in table 1 may be marked as suitable for use with additional lamps beyond those shown in the table. ANSI C78.180-2003 (

44、voltage shall be equal to the rated voltage of the ballast or for certain tests, the voltage specified in this standard. During periods of stabilization, the supply shall be stable within +0.5%. This tolerance is reduced to +0.2% during measurement. The waveshape of the supply voltage shall be a sin

45、e wave, and shall have a waveshape such that the root-mean-square (rms) summation of the harmonic components shall not exceed 3% of the fundamental for all conditions which occur during the measurement. NOTE: This implies that the source of the supply should have sufficient power, and that the suppl

46、y circuit should have a sufficiently low impedance, compared with the ballast impedance. 6 Ambient Conditions for Testing 6.1 Temperature The ambient temperature shall be 25C 5C (77F 9F). 6.2 Humidity The relative humidity is not restricted. 7 Test Lamps 7.1 Type When lamp starting-time or endurance

47、 tests are made on starters, the fluorescent lamps used shall be the principal type for which the starter was designed. 7.2 Seasoning and Selection of Lamps for Starting-Time Tests Commercially available lamps, of recent manufacture, recommended for use in preheat (Switch) start circuits shall be us

48、ed. Where several lamp types are used with a given ballast-starter combination, the most popular lamp type shall be used. a) For F4T5, F6T5, F8T5use F8T5 lamps. b) For F14T12, F15T12, F20T12use F20T12 lamps. To avoid the possibility of using lamps of poor quality, the lamps shall be seasoned a minim

49、um of 100 hours and shall be selected to have operating voltages within 2.5 percent of rated operating voltage as given in American National Standard C78.81 or C78.901. Lamps shall be replaced if an appreciable degree of end discoloration is visible. Lamps showing swirling or other abnormal conditions should not be used. ANSI C78.180-2003 (R2016) Page 5 2016 National Electrical Manufacturers Association 7.3 Lamps for Lamp Starting Endurance Tests Lamps shall be commercial products of good quality and less than two years old. 7.4 Lamps for De
