Problems solved by technology
However, there are many sensitive components in the control board of gas equipment. Under high-intensity electromagnetic radiation, the control board will be interfered by the electromagnetic radiation, which will cause its internal signal to be disordered, and then cause the gas equipment to reset and crash.

The invention discloses a method and device for detecting the anti-electromagnetic radiation ability of a control board. By starting a preset number of high-voltage coils, the high-voltage coils are used to generate high-voltage electric energy, and the high-voltage power is transmitted to the ignition wire connected thereto. The ignition wire In the case of electrification, the electric field and magnetic field change alternately, and then electromagnetic radiation can be generated around the ignition wire. Placing the control board in the electromagnetic radiation field formed by the ignition wire can effectively simulate the interference of the electromagnetic radiation on the control board when the gas product is ignited. When the tested control board works normally, it can judge its anti-electromagnetic radiation ability Qualified, and then realize the anti-interference ability detection of the tested control board, which is convenient for subsequent product rectification design.
Description
technical field [0001] The present application relates to the field of electrical technology, in particular to a method and device for detecting the electromagnetic radiation resistance capability of a control board. Background technique [0002] Existing gas appliances such as gas stoves and water heaters mostly adopt electronic ignition, for example, use a pulse igniter to ignite. [0003] Specifically, the pulse igniter is a pulse high-frequency oscillator composed of electronic components. The high-frequency voltage generated by the oscillator is raised to a high voltage of 15KV through a step-up transformer, and the high-voltage electricity generated is transmitted to the The ignition needle, and then use the ignition needle to perform tip discharge, and finally the gas on the gas equipment is ignited by the spark of the discharge. However, during the working process of the pulse igniter, after the ignition wire connected to it is energized, the alternating electric fi...
