Embodiment Construction

[0030] The overall size of the test cabinet is 1200×1200×1200, the height ratio of the test bench and the observation cover is 1:1, each is 600mm.

[0031] The test bench panel is made of 1110×1110×25 electrical asbestos cement board, which can withstand a temperature of 1200°C and a voltage of 1.5KV / mm, and has good insulation. The panel is embedded on the test bench frame.

[0032] The observation cover is made of plexiglass plate (glass plate can also be used, but it must be treated with explosion-proof treatment), which is easy to observe the test state of the specimen, and the observation cover and the test bench are connected by hinges.

[0033] The travel switch is selected as the power-off protection, and when the observation cover is opened, the test cabinet is automatically powered off, effectively protecting the safety of operators. The limit switch is installed on the test platform, the observation cover is closed, the limit switch is turned on, and the workin...

Abstract

The invention relates to a test object cabinet for testing anticipated short-circuit current of an SPD (surge protection device). The test object cabinet has an airtight, visual and closed structure capable of discharging smoke dust and disconnecting power supply after being opened. A movable organic glass observation cover is mounted on a test bench surface to facilitate observation and operation; a centrifugal exhaust fan is connected with an air inlet on the test bench surface and an air outlet on the cabinet wall; and the centrifugal exhaust fan can promptly exhaust smoke dust generated by burning the test object. The test object cabinet with the closed structure can effectively protect the personal safety of test personnel in case of an accident.

Description

[0001] technical field [0002] The invention relates to the field of test cabinets that provide safety protection for simulation experiments of electronic and electric power products. To be precise, it provides a kind of test equipment that can supply Safely protected SPD prospective short-circuit current test cabinet. Background technique [0003] At present, in the field of domestic lightning protection technology, there is no relatively complete and complete experimental equipment for thermal tripping of expected short-circuit current. Most of the experimental equipment is tested in an open environment, and the test is carried out under high voltage and high current conditions. There is the possibility of combustion and explosion, which is a great potential safety hazard, and also a great threat to the life safety of operators. Contents of the invention [0004] The purpose of the present invention is to provide an airtight, visible, power-on and power-off device tha...
