Problems solved by technology

The withstand voltage test is a high-voltage test, and there are many danger sources, which increase the potential safety hazard of electric shock for operators
For example, only test personnel with a special operation certificate (high voltage) can operate the withstand voltage machine, and other unqualified personnel may have potential safety hazards; during the withstand voltage test, insulating gloves and insulating boots must be worn to prevent equipment failure from causing personnel failure. electric shock
During the withstand voltage test, once the door of the withstand voltage cabinet is opened, it is very dangerous, and the test personnel are prone to electric shock
The safety protection of the traditional withstand voltage test does not run through the entire withstand voltage test process for protection and supervision. The method of operating the withstand voltage machine is too traditional, and the high-voltage test has a high risk of electric shock
Secondly, the traditional withstand voltage test has no data storage function, and most of them are paper version
Finally, the withstand voltage test is manually controlled, which has potential safety hazards

Embodiment 1

[0049] In a typical embodiment of the present invention, such as figure 1 As shown, a withstand voltage test system is proposed, including a withstand voltage machine 1, a measurement and control module 2, a monitoring module 3, a power supply module 4, and so on.

[0050] The pressure-resistant machine is an intelligent and safe pressure-resistant machine. The pressure-resistant machine is powered by the power module, which communicates with the measurement and control module. The measurement and control module controls whether the power module is powered by the pressure-resistant machine; the monitoring module collects the video / video of the pressure-resistant machine test process. image, and the monitoring module communicates with the measurement and control module, and transmits the video / image to the measurement and control module.

[0051] Among them, the output test voltage of the power module can be continuously adjusted in the range of AC (0-15) kV, the leakage curren...

Embodiment 2

[0076] Provide a kind of railway vehicle pressure test method in this embodiment, its test process is:

[0077] (1) Before the pressure test: the operator of the pressure test turns on the camera to record the whole process of the pressure test of the pressure machine.

[0078] Spot-check the pressure-resistant machine to verify that the pressure-resistant machine is functioning normally. Through the network monitoring of the camera, the point inspection status record of the pressure machine, vehicle status, and pressure tooling status is carried out.

[0079] The operator of the pressure-resistant machine starts the intelligent pressure-resistant machine and logs in the software of the pressure-resistant machine through the fingerprint identification module. The pressure-resistant test is judged by the fingerprint identification system, whether the operator has a special operation certificate, and one-key login is realized.

[0080] The intelligent pressure-resistant machine...

Abstract

The invention discloses a withstand voltage test system and method. The withstand voltage test system comprises: a withstand voltage machine; a measurement and control module communicating with the withstand voltage machine and used for controlling whether the withstand voltage machine works or not; a monitoring element communicating with the measurement and control module and used for monitoring the current change of the withstand voltage machine, wherein if the current exceeds a set value, the measurement and control module controls the withstand voltage machine to stop working; and a protection device, wherein the withstand voltage machine is arranged in the protection device, the protection device is provided with a door body capable of being opened and closed, a limiting switch is arranged at the door body, and the limiting switch communicates with the measurement and control module.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle pressure test, and in particular relates to a pressure test system and a test method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the insulation withstand voltage test of rail vehicles has become an indispensable test item. The withstand voltage test is a high-voltage test, and there are many sources of danger, which increase the potential safety hazard of electric shock for operators. For example, only test personnel with a special operation certificate (high voltage) can operate the withstand voltage machine, and other unqualified personnel may have potential safety hazards; during the withstand voltage test, insulating gloves and insulating boots must be worn to prevent equipment failure from causing personnel failure. electric shock. During th...
