Problems solved by technology
The microcomputer protection device is an isolated spare part from the factory, and the wiring of micro-protection equipment from different manufacturers is also different. It is very cumbersome and unsafe to test and verify the separate wiring and wiring; infrequent operation will lead to replacement of the microcomputer protection device and the test time of setting value Longer, it is also prone to wrong setting or not setting the value, resulting in the failure of the protection function, and problems such as failure to find the closing and opening circuit of the micro-protection protection device of the high-voltage cabinet; especially in multi-type, multi-type, multi- In the case of a large number of equipment, the task of equipment maintenance is heavy. Replace the microcomputer protection device, perform protection switching and setting values, conduct protection experiments, and simulate various secondary faults. Constant re-wiring is required and is cumbersome and complicated. The wiring and experiments do not meet the specifications. Personal safety is not guaranteed, the efficiency of replacing the micro-protection device is low, and the quality of the test is not high, etc.

Embodiment Construction
[0018] The technical solutions of the present invention will be clearly and completely described below through specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0019] Such as figure 1 As shown, the protection device is a vertical cabinet, which is mainly composed of a front cabinet panel and a rear cabinet panel. Its interior is layered and partitioned to set up microcomputer protection (1), power supply circuit breaker and terminal block; several microcomputers are fixed on the upper part of the front cabinet panel. Protection (1), the middle part is the switch and indicator light area (2) to install the common closing switch, closing indicator light, opening switch, and position i...

The invention relates to the technical field of microcomputer protection, in particular to a protection device for protecting various microcomputers, which is a vertical cabinet and mainly comprises a front cabinet panel and a rear cabinet panel, and microcomputer protectors, power supply air switches and terminal strips are arranged in the vertical cabinet in a layered and partitioned manner. Under the condition of multi-type, multi-type and multi-number microcomputer protection, in the processes of microcomputer protection replacement, protection experiment, protection switching constant value and simulation of various secondary faults, personnel safety is guaranteed, the micro protection device replacement efficiency is improved, and the experiment and troubleshooting quality capability is improved.
Description
technical field [0001] The invention relates to the technical field of microcomputer protection, in particular to a protection device for various microcomputer protections. Background technique [0002] As the core of commonly used high-voltage protection, the microcomputer protection device is used for over-current protection, quick-break protection, low-voltage protection of high-voltage cabinets, process interlock protection such as: low oil pressure, frequency conversion fault, DCS total fault, etc., and body protection such as: Light gas, heavy gas, high temperature, over-temperature protection, etc.; according to the use of the load, set the value according to the actual situation and perform protection switching on and off. The microcomputer protection device is an isolated spare part from the factory, and the wiring of micro-protection equipment from different manufacturers is also different. It is very cumbersome and unsafe to test and verify the separate wiring and...
