Embodiment 1

[0038] This embodiment provides a figure 1 The overcurrent protector automatic test device shown.

[0039] The overcurrent protector automatic test device of the present embodiment comprises:

[0040] Base device: the base device is provided with a power switch 5, a cylinder button 4, a stop button 13 and a display screen 12, the power switch 5 is used to control the power on and off of the whole device, the cylinder button 4 is used to start the cylinder, and the stop button 13 is used to The cylinder is stopped, and the display screen 12 is used to display the test result information. The base device is also provided with a logic judgment module (not shown in the figure), which is used to input analog current to the overcurrent coil, monitor the output voltage and / or action of each overcurrent element, and judge whether the overcurrent protector is abnormal.

[0041] Driving device: This embodiment uses pneumatic drive, that is, the cylinder 6 is installed on the bracket 7...

Embodiment 2

[0047] This embodiment provides a figure 2 The overcurrent protector automatic test system shown.

[0048] The overcurrent protector automatic test system of the present embodiment comprises:

[0049] The drive module is used to drive the movement of the overcurrent board, so that the overcurrent board is connected with the logic judgment module;

[0050] The flow plate is provided with a flow element, and the flow plate is driven by the drive module to move;

[0051] The logic judgment module is used to input analog current to the overcurrent coil, monitor the output voltage and / or action of each overcurrent element, and judge whether the overcurrent protector is abnormal;

[0052] The prompting module is used for prompting the output voltage value and / or action status of each overcurrent element, and the prompting methods include a display interface and / or an audible and visual alarm.

[0053] Optionally, the automatic test system for the flow protector further includes ...

Embodiment 3

[0055] This embodiment provides an automatic testing method for an overcurrent protector.

[0056] The automatic test method of the overcurrent protector in this embodiment is: input the analog current to the overcurrent coil of the overcurrent protector, and judge the overcurrent protector Is it abnormal.

[0057] The overcurrent components tested by the method include overcurrent coils and / or current transformers and / or voltage stabilizing blocks and / or comparators and / or relays.

[0058] When the output voltage of the overcurrent coil is less than 4.3V, it is judged that the current protector is abnormal; when the output voltage of the current transformer is less than 4.3V, it is judged that the current protector is abnormal; when the output voltage of the voltage stabilizing block is less than When 11.5V or greater than 12.5V, it is judged that the current protector is abnormal; when the output voltage of the comparator is less than 4.3V or the comparator does not operate...

Abstract

The invention discloses an automatic test method, a system and a device for an overcurrent protector. The method comprises the following steps: inputting an analog current to the overcurrent coil of the overcurrent protector; judging whether the overcurrent protector is abnormal or not by monitoring the output voltage and/or the action condition of each overcurrent element of the overcurrent protector. According to the automatic test method, the system and the device for the overcurrent protector, an automatic monitoring of various parameters in the whole testing process is realized by simulating current driving; by inputting the analog current to an overcurrent coil pin to trigger a coil action, the operation inconvenience caused by manual test is solved, and the operation risk is eradicated, thereby effectively preventing a controller from being damaged by an overcurrent caused by ignition of the coil, effectively improving situations of the overcurrent damage of the controller, eradicating missing detection, misoperation and the like, and meanwhile, improving the testing efficiency; comparing to a manual testing, a lot more test points are added, thereby greatly optimizing the operation steps, improving the testing efficiency, and ensuring the qualified rate of the test product to be 100%.

Description

technical field [0001] The invention relates to an automatic testing method, system and device for an overcurrent protector, in particular to an automatic testing method, system and device for an air conditioner overcurrent protector. Background technique [0002] At present, over-current protectors are tested manually. The inspector passes the wire through the current transformer, supplies a strong current to the over-current coil and relies on ignition to trigger the coil to generate an over-current, triggering the protector to compare the chip action. At the same time, it may also be due to the stability The test is uncontrollable due to the wrong use of the briquetting block. [0003] The invention patent with the publication number CN102313848A discloses an overcurrent protector detection device, which includes an overcurrent protector circuit, and the circuit includes an AC terminal, and the AC terminal is connected in series with the power switch, voltage regulator an...
