3.1 Ballast ballast
A device connected between the power supply and one or more discharge lamps. Its main function is to limit the lamp current to the required value by relying on inductance, capacitance, or a combination of inductance and capacitance. Ballasts may also include components that vary the supply voltage, provide auxiliary starting voltage, prevent cold starts, reduce stroboscopic effects, correct power factor, and suppress radio frequency interference.
a. Independent ballast symbol: independent ballast can be installed outside the lamp without the need for an additional casing. It may also be a built-in ballast with an enclosure that provides the required protection as marked.
b. Built-inballast is a ballast specially designed to be installed in a lamp, box or casing. The control room within the light pole base is considered a housing. c. The integral ballast becomes an irreplaceable part of the lamp and cannot be tested separately from the lamp. The State Bureau of Technical Supervision approved it on 1993-01-04 and implemented it on 1993-07-01
3.2 Reference ballast referenceballastGB14045—9.3
A ballast specially designed for testing ballasts and selecting reference lamps. Its main feature is a stable voltage-to-current ratio at rated frequency, which is relatively unaffected by changes in current, temperature and surrounding magnetic fields. 3.3 Reference lamp referencelamp
The lamp selected for testing the ballast. When the lamp is matched with the reference ballast and works under specified conditions, its electrical characteristics are close to the nominal values ??stipulated in the relevant lamp standards. bzxz.net

5 Technical Requirements
5.1 General Requirements
GB14045-93
Ballasts should be designed and constructed so that they can Without causing harm to users or the surrounding environment, the capacitors and other components in the ballast should comply with relevant standards. 5.2 Safety requirements
5.2.1 Protection against accidental contact with live parts Ballasts that do not rely on the lamp housing to prevent electric shock should be able to fully prevent accidental contact with live parts when installed according to normal use conditions.
Varnishes and enamels are protective or insulating measures that do not meet this requirement. Parts used to prevent accidental electric shock should have sufficient mechanical strength and must not be loose during normal use. They cannot be removed without tools. tear down.
Ballasts equipped with internal capacitors with a total capacitance exceeding 0.5μF should have a discharge device. When the ballast is disconnected from the power supply at rated voltage for 1 minute, its terminal voltage should not exceed 50V. 5.2.2 Terminals
Threaded terminals shall comply with the requirements of Chapter 13 of GB7000. Threadless terminal blocks shall comply with the requirements of Chapter 14 of GB7000. 5.2.3 Grounding device
5.2.3.1 All grounding terminals shall comply with the requirements of Article 5.2.2. Electrical connections should be sufficiently locked to prevent accidental loosening and should not be loosened by hand. For threadless terminals, they should not be loosened at will. The ballast is allowed to be grounded by means of a device that secures the ballast. However, if the ballast is equipped with a ground terminal, this terminal may only be used for grounding the ballast.
5.2.3.2 All parts of the grounding terminal shall be designed to minimize the hazards of electrolytic corrosion due to contact with the grounding conductor or any other metal parts.
The screws or other parts of the ground terminal should be made of brass, other metals with corrosion resistance no less than brass, or materials with anti-corrosion coating and at least one of the contact surfaces should be exposed metal. production. 5.2.4 Moisture-proof and insulation performance
The ballast should have good moisture-proof performance and insulation performance. 5.2.4.1 The ballast shall not be damaged after being subjected to the humidity test. 5.2.4.2 There should be sufficient insulation between the following components, and the insulation resistance measured after the test specified in Article 6.5 shall not be less than 2M2.
