Integrated low pressure monitoring device

Abstract

The invention discloses an integrated low pressure monitoring device. The front end of the device is connected with a breaker. The device comprises a voltage transformer, a current transformer, an electric power metering module, a CPU processor and a display panel. The voltage transformer, the current transformer, the electric power metering module and the CPU processor are integrated to form an integrated CT module. The display panel and the integrated CT module are detachably connected. The breaker is connected with the voltage transformer and the current transformer separately. The voltage transformer and the current transformer are both connected with the CPU processor through the electric power metering module. The display panel is connected with the CPU processor. The beneficial effects are as follows: wiring is simple and fast; the device does not need to be connected with an external current loop; the device is beautiful in look; only the integrated CT module needs to be installed; the device is high in stability and improves the work efficiency; the check content is not much; the error test rate is reduced; the running status can be directly reflected; and background monitoring, remote monitoring and remote maintenance can be achieved.

Description

technical field [0001] The invention relates to the related technical field of low pressure monitoring, in particular to an integrated low pressure monitoring device. Background technique [0002] In the traditional low-voltage complete switchgear, the terminal equipment is monitored through current transformers and analog pointer meters, and the voltage is often not monitored. As a result, the monitoring of the actual operation of the load is very scarce, and the terminal equipment cannot be fed back in detail. The power consumption situation has caused the phenomenon that the capacity of some terminal equipment is too large or overloaded. [0003] The times are advancing, and the traditional low-voltage complete switchgear is gradually being innovated and improved. Multi-functional network instruments are promoted, relying on current transformers to collect current, protecting and collecting voltage from the line side through fuses, and processing calculations through CPUs...

Problems solved by technology

[0004] However, the multi-functional network instrument has the disadvantages of large volume and complicated wiring. Due to the complicated wiring of the current acquisition circuit and the voltage acquisition circuit, the wiring process is very difficult to control, and the production input cost increases. Greater improvement is required in terms of structure and process.
