Embodiment Construction

[0024] The accompanying drawing is a structural diagram of the tested HID ballast, which consists of a high-voltage package 1, a switch tube 2, a diode 3, a Moss tube 4, a transformer 5, a control IC6, a freewheel resistor 7, a time capacitor 8, a time resistor 9, An energy storage capacitor 10, a constant current capacitor 11, an ignition capacitor 12, a reverse protection tube 13 and an adjustable resistor 14 are formed.

[0025] The present invention is realized by the following technical scheme: the maintenance method of the HID ballast, equipped with tools include: multimeter, 12V DC power supply, digital ammeter, flashover test stand, xenon bulb.

[0026] The first step is to connect the output line of the tested HID ballast to the flashover test stand, and connect the positive and negative poles of the 12V DC power supply to the positive and negative poles of the ballast;

[0027] The second step is to turn on the power of the 12V DC power supply, the switch tube 2 of t...

Abstract

Disclosed is a maintenance method of an HID (high intensity discharge) ballast. Tools such as a multimeter, a 12V direct-current power supply, a digital ammeter, an arcing test rack, and a Xeon bulb are provided. The arcing test rack is composed of two Z-shaped steel wires. A lead is welded to the bottom end of each Z-shaped steel wire. The top ends of the two Z-shaped steel wires are opposite. The bottom ends of the Z-shaped steel wires are locked on a wood board. The anode-cathode test rack is provided with a 7mm gap. The method has the advantages that parts of the ballast can be quickly tested by the method, and maintenance efficiency is improved evidently.

Description

technical field [0001] The invention relates to a maintenance method for a motor vehicle lighting ballast, in particular to a maintenance method for an HID ballast. Background technique [0002] The ballast is the control part of the HID xenon lamp. Because it works in a harsh high-temperature environment, the damage of internal parts is inevitable. The hidden or dominant faults in the return and production will bring serious damage to the manufacturer and maintenance personnel. workload. Contents of the invention [0003] The purpose of the present invention is to provide a method for overhauling the HID ballast, which can quickly overhaul the damaged part of the ballast. [0004] The present invention is realized by the following technical scheme: the maintenance method of the HID ballast, equipped with tools include: multimeter, 12V DC power supply, digital ammeter, flashover test stand, xenon bulb. [0005] The first step is to connect the output line of the fail st...
