Problems solved by technology

[0005] At present, there are very few monitoring devices for ultra-high-current instruments and equipment whose working current reaches hundreds of amps. During installation, the monitored instrument needs to be powered off, which takes a long time to deploy and is inconvenient to install. When monitoring, it cannot meet the demand
Moreover, these devices are generally local monitoring and local display, and cannot be monitored online, so the use cannot meet the needs

Embodiment 1

[0033] A kind of ultra-high current monitor, its composition comprises: current transformer 1, casing 2, described current transformer is installed on the outside of described casing, and ammeter 3, controller 4, Alarm device 5, power module 6, knob 7, the signal input end of the ammeter is connected to the signal output end of the current transformer, the communication end of the controller is connected to the communication end of the ammeter, the The alarm device is connected to the control terminal of the controller, the power module is connected to the ammeter, the controller, and the alarm device; the knob enables, Disability.

Embodiment 2

[0035] In the ultra-large current monitor described in Embodiment 1, the current transformer converts the hundred ampere current signal of the power supply cable of the instrument under test into an ampere current signal, and outputs it to the ammeter, and the control The device continuously reads the current value data in the ammeter, and uploads the current value data to the remote instrument monitoring system through the wireless communication module inside the controller; the controller performs the reading on the current value Judging, giving an alarm to the current exceeding the set threshold, and uploading the alarm information to the remote instrument monitoring system.

Embodiment 3

[0037] In the ultra-large current monitor described in Embodiment 1, the current transformer is a split type, and is directly placed on the instrument power supply phase line during installation, and the number of current transformers is 1 to 3; the ammeter contains a wired communication interface. The three-phase digital display ammeter, the controller reads the current value data through this interface, and the three-phase digital display ammeter displays the current value in real time; the current transformer and the ammeter are electrically connected at the bottom of the box through an aviation plug; The controller includes a main control module, a wired communication module, a wireless communication module, a relay module, and a power supply module. The controller communicates with the ammeter through the wired communication module, and communicates with the ammeter through the wireless communication module. The module communicates with the remote instrument monitoring sys...

Abstract

The invention provides an ultra-large current monitor. The product comprises: a current transformer and a box body, wherein the current transformer is installed on an outer side the box body, an ampere meter, a controller, an alarm device, a power module and a rotary knob are installed in the box body, a signal input end of the ampere meter is connected with a signal output end of the current transformer, a communication end of the controller is connected with the communication end of the ampere meter, the alarm device is connected with a control end of the controller, and the power module isconnected with the ampere meter, the controller and the alarm device; and the rotary knob enables and disables the alarm device. The invention is applied to the ultra-large current monitor.

Description

[0001] Technical field: [0002] The invention relates to a super large current monitor. [0003] Background technique: [0004] Instruments and equipment are the basic conditions for production, scientific research and technological innovation, and are an important symbol to measure the level of a country's scientific and technological development. With the rapid development of social economy and the advent of the era of knowledge and information, people use instruments and equipment more and more frequently, and the resulting demand for instrument management is also increasing, especially for some The monitoring of advanced instruments and equipment has attracted more and more attention. [0005] At present, there are very few monitoring devices for ultra-high-current instruments and equipment whose working current reaches hundreds of amps. During installation, the monitored instrument needs to be powered off, which takes a long time to deploy and is inconvenient to install....
