Definitions
- the present invention relates to the field of low voltage electrical appliances, and in particular to time relays.
- metal halide lamps have many advantages as a new type of light source.
- the secondary power-on must be performed after cooling. Otherwise, the high voltage generated by the trigger is likely to burn out the trigger pole and the main electrode lead of the lamp.
- the reason is that the gas pressure in the lamp is very high when the metal halide lamp is in the ignition state, and the gas pressure is low in the cooling state.
- the breakdown voltage of the ignition is related to the gas pressure and the electrode distance. The higher the gas pressure, the higher the starting voltage. The more difficult it is to start, if the power is re-energized without cooling, the trigger will generate a very high voltage to illuminate the light source, which will shorten the life of the light source.
- the life test cycle is to turn on the lights for 11 hours and turn off the lights for 1 hour.
- a time relay for the metal halide lamp is needed, which is used to control the on/off of the power supply of the metal halide lamp, and has an automatic delay time and delay after the power is turned off.
- the function of the relay output circuit can be turned on to realize the control of the secondary power-on start after the time required for the cooling of the metal halide lamp to be extinguished.
- the time relay for this metal halide lamp is not only used for metal halide lamps, but also for other loads that are the same as the delay control process for gold lamps, which will include such loads as gold 13 ⁇ 4 lamps.
- the time relay used is called a time relay for a metal halide lamp type load.
- the time relay for the metal halide lamp load has the following delay control process: When the time relay is connected to the power-off signal synchronized with its output contact, the timing control circuit starts timing and goes through a long delay process. In this delay process, the output contact is always disconnected regardless of whether the power is restored or not. After the delay process ends, the output contact continues to be disconnected if it is still in the power-off state. If the current state is still energized, the output contact is switched. To close.
- the existing time relay cannot be directly used as a metal halide lamp load because of: logic function
- the delay requirement of the secondary power-on start of the metal halide lamp load cannot be met.
- the logic requirement of the metal halide lamp delay control is to start the delay time after the light source is turned off (ie, the output contact of the time relay is disconnected). After the delay is over, the output loop of the relay is allowed to be turned on (that is, the output contact of the time relay is allowed to be closed), and its logic function is as shown in the logic timing diagram of the metal halide lamp type load, and the existing time.
- the logic function of the relay is usually to start the delay timing after receiving the action signal (the action signal is not necessarily related to the on/off of the output contact of the time relay), and the output circuit of the relay is turned on/off after the delay is over.
- the state ie, the output contact of the time relay is closed/disconnected
- produces a jump transition the logic function of which is the logic timing diagram of the existing time-delay time relay shown in Figure 1;
- the delay time of the existing time relay Short generally only can achieve delay control within 3 minutes, but the cooling time of metal halide lamp takes 20 minutes, too short delay can not meet the cooling requirements of metal halide lamp;
- the output current of the time relay has a small operating current (generally below 5A), which cannot be used to directly control the high-power metal halide lamp; the existing product has no status indicator during the delay control after power-off, which is inconvenient to use. , not intuitive.
