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...

Problems solved by technology

[0006] Although the above-mentioned environmental protection monitoring equipment realizes the function of power collection, its voltage and current sampling methods are complicated, and the site not only needs to be connected to a current transformer or a Hall sensor, but also needs to be connected to a strong current through a wiring clip to be able to collect the cross-collection data. voltage, so as to realize the power harvesting function

In some installation conditions, due to the small installation space, it is easy to cause wiring confusion, wrong wiring, electric shock, short circuit protection and other problems
