Low pressure cabinets require a variety of tests to ensure their performance and safety, these tests mainly include:
Mechanical debugging: mainly involves the debugging of hand operated parts and drawers, testing whether each mechanism is flexible and reliable. In particular, when the drawer is inspected, it is necessary to pay attention to whether the connection and disconnection position is reliable, which will affect the normal use of the low-voltage distribution cabinet.
Electrical debugging: including electrical operation experiment, simulated action test such as circuit breaker closing, opening operation, button operation and related indicators are normal. There is also an interlock function test to check the interlock of the mechanism and the door to ensure that the door cannot be opened in the case of power, and the switch can be opened after the switch is opened.
Insulation resistance test: In order to ensure the safety of the operator, the cabinet and the devices in the cabinet, test the switch off position, the same pole inlet line, the outlet line position, the insulation resistance between the different pole live parts when the main switch is closed, between the main circuit and the control circuit, and between the live elements and the metal frame, the test should reach 1 minute, and the insulation resistance should reach more than 0.5M ohms.
Structural and performance testing: including the protection level of the housing, electrical clearance and creepage distance, shock protection and the integrity of the protection circuit, the combination of internal components, internal circuits and connections, external wire terminals, mechanical operation, etc.
Routine inspection items: In addition to the above tests, it also includes dielectric property testing. According to the requirements of power frequency withstand voltage test, power frequency withstand test is carried out on all circuits, but the duration is 1 second.
They are designed to operate within a wide range of temperatures and humidity levels, resist dust and moisture, and be suitable for both indoor and outdoor applications.
Installation requirements typically include adherence to local electrical codes, proper grounding, secure mounting, and ensuring easy access for maintenance and operation.
