Description

Explosion-proof high-voltage generator

Technical Field

The utility model relates to a torch ignition technique, especially explosion-proof high pressure generator.

Background

At present, most of explosion-proof high-voltage generators used by people use direct current transformation, and the direct current transformation pulse is higher; the voltage output is unstable; the housing is not firm.

Disclosure of Invention

The utility model aims at providing an explosion-proof high-voltage generator with long service life, which solves the problems of other technologies and comprises a shell, a connecting terminal, a temperature limiting module, an AC transformer and a grounding terminal, wherein one side of the shell is fixed with the connecting terminal; the wiring terminal is respectively connected with the temperature limiting module and the alternating current transformer.

The temperature limiting module is connected with the alternating current transformer.

One end of the alternating current transformer is connected with a grounding end, and the grounding end is connected with the torch tower.

The utility model discloses an application method: the grounding end of the explosion-proof high-voltage generator is connected with a torch tower, an igniter is welded on a torch head, two output ends of the explosion-proof high-voltage generator are connected with a high-voltage cable to an ignition electrode of the igniter, the ignition distance is 5-8mm, when one high-voltage cable is not well insulated and is short-circuited or broken, the other high-voltage cable is well insulated, the distance between the ignition electrode and the wall of a DN20 stainless steel pipe needs to be adjusted, and the distance is 5-8mm, so that when one high-voltage cable fails, the other high-voltage cable can still normally ignite; when the ignition operation is carried out, the explosion-proof high-voltage generator is required to be not later than the fuel gas valve opening time, the pipeline can act simultaneously when being longer, the high-voltage generator needs to be started firstly when the pipeline is shorter, the fuel gas valve is opened after 2 seconds, when a power supply is sent into the explosion-proof high-voltage generator, the power supply enters the alternating current transformer through the temperature limiting module, and the power supply is transmitted into other devices through the high-voltage output end after being output by the alternating current transformer. The transformer adopts alternating current, and is different from direct current transformation: the pulse interference is reduced, and the stable output of the voltage is ensured. On the other hand, the grounding end is additionally arranged, so that the possibility of damage to one path in the two-path output can be effectively avoided, and the service life of the high-voltage generator is prolonged. In the structural design of the explosion-proof high-pressure generator, the epoxy resin is used to encapsulate the whole interior of the high-pressure generator in consideration of the fact that the explosive mixture does not enter the high-pressure generator, and the explosion-proof performance of the generator is ensured by the strength of the shell, the maximum surface temperature of the shell and the like.

The utility model discloses a meaning: the model temperature fuse of the current limiting module is ST-22110 degrees; the ZB-JLBQ-I220 VAC of the alternating-current transformer is changed into a double-circuit output 2 x7.5KV; the explosion-proof high-voltage generator is an important component of a torch automatic ignition system, has the function of receiving a program control signal to generate high voltage, has safety-increasing type explosion-proof performance, can simultaneously output 2 multiplied by 7.5KV voltage, can still normally ignite one path when the other path fails, has protective measures of voltage limiting, current limiting, temperature limiting and the like, and is long in service life, safe and reliable. The input power voltage is 220VAC, the high voltage generator generates output voltage of 2X7.5KV +/-10% AC, and the output voltage is used as an ignition power supply and is sent to a high-altitude igniter. This explosion-proof high voltage generator designs for low energy consumption product, and the temperature rise is lower, explosion-proof high voltage generator input voltage: AC220V +/-10% input current is less than or equal to 4A; output voltage: 2 × 7.5KV output current: 30 mA. However, in order to prevent the temperature from suddenly rising due to the short circuit of the output end, the temperature limiting module is arranged in the high-voltage generator, when the heat in the shell works for a long time is accumulated and the temperature rises to exceed 105 ℃, the power supply is automatically cut off by the module, the high-voltage generator stops working, and when the temperature drops to be lower than 105 ℃, the power supply channel automatically recovers.
