Abstract

The invention discloses an environmental protection monitoring device, comprising a voltage sampling unit, a current sampling unit, a device base, a circuit functional unit, and power and signal cables, wherein the voltage sampling unit and the current sampling unit are connected to the device base; a cable under test is clamped in via an open structure; the circuit functional unit is mounted in the device base; the power and signal cables are connected inside; the voltage sampling unit is used for acquiring a voltage sample signal of the cable under test; the current sampling unit is used foracquiring a current sample signal of the cable under test; the circuit functional unit is used for processing the voltage sample signal and the current sample signal. The power and signal cables areused for providing access for power and transmitting signals. The voltage and current sampling modes of the environmental protection monitoring device can be simplified; the environmental protection monitoring device is convenient to install.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to environmental monitoring equipment. Background technique [0002] For environmental protection monitoring, the traditional solution is completed by using a current transformer. The current transformer is composed of a primary transformer and a secondary transformer (generally called an instrument transformer, installed in a collector), which is large in size and high in cost. Restricted installation is difficult, and even some branch circuits need to be modified to install; there are many branch circuits in the power consumption unit, and each circuit needs to be connected to current transformers, collectors, communication equipment and other equipment, and the equipment cost is high; The voltage signal is connected to the branch circuit, and a power outage operation is required during installation, which will affect the production and operation activities of the...
