Electrostatic precipitator cathode vibrating porcelain shaft box dust-proof plate, cathode hanging insulator room dust-proof plate creepage: When the no-load boost test, the surface of the insulating plate is clean, no breakdown discharge, and the boost test is qualified. When the electrostatic precipitator is put into operation, the surface of the dust-proof plate begins to hang ash, and the temperature of the cathode rapping porcelain shaft box and the cathode suspension insulator room is lower than that of the dust precipitator. The temperature difference between the two sides of the insulation plate is relatively large, and is 90-120°C ( The smoke temperature is 145°C and the box temperature is slightly higher than the ambient temperature). The dust-proof plate dew and gray out on the inner surface, and the insulation level is reduced. Under the action of high voltage, “climb creep†phenomenon occurs and breakdown occurs. The long-term discharge also causes carbonization of the dustproof board surface, so that the voltage of the call field flashes frequently and cannot be operated at high voltage, and the efficiency of the electrostatic precipitator will be reduced.
Electrostatic precipitator pole pitch exceeds the standard: pole plate sediment beam hole, rapping with hole size deviation, plate row installation accuracy, limit channel installation is not standard, when the plate thermal expansion is limited, the occurrence of side bend (polar When the plate expands downwards, it is limited to 1mm each, and a side bend value of up to approximately 30mm occurs. This results in a pole pitch that does not meet the design requirements.
The electrostatic precipitator puncture line is broken: After the disconnection, the polar line oscillates back and forth under the action of air flow, vibrating, etc., and discharges in advance. At this time, the voltage and the current suddenly become large and small and unstable. In case of serious direct short-circuit, the plate is broken down and no dust removal effect is achieved.
In summary, the main reasons for voltage flashover are caused by the distance between the cathode insulation, dust accumulation on the dust-proof plate, the asymmetry of the anode plate, and the exceeding of the pole pitch caused by the breakage of the burr line.
Type of LED Light Strip: LED hard light strip or PCB light strip
The length of this kind of lamp belt is fixed and not easy to bend. Generally, there is a pad at the bottom for connecting wires. For example, let the light band COM-12022.
This light strip is a circuit structure composed of three LEDs in series and parallel. This structure allows the light strip to be cut to the required length. The lamp belt can be driven by the rated constant voltage LED driver with the required voltage, and the driving current is equal to or greater than the required current; After the length and swing voltage are determined, the constant current driver with accurate current can also be used for driving.
In addition, there are some pre-wired fixed light strips. For example, OVM12F3W7.
