A feeder circuit online monitoring module

Abstract

The present invention provides an online monitoring module for a feeder circuit, comprising: a switch body, a monitoring device and a circuit cable, wherein the monitoring device is fixed to the switch body by screws. The monitoring device is directly fixed to the switch body to achieve accurate collection of voltage and temperature, and there is no secondary line for voltage and temperature collection, and the temperature collection is pre-buried in the conductor, so the collection accuracy is higher. Since it is directly hung on the switch body, the structure of the power distribution system is not changed, and it can be adapted as long as there is a switch, with high flexibility and a wide trial range. The device has no relationship with the primary cable, reduces the primary circuit fault point, and improves safety.

Description

Technical Field

[0001] The invention relates to the technical field of online monitoring, and in particular to an online monitoring module for a feeder circuit. Background Art

[0002] The monitoring device is one of the most widely used devices in power distribution equipment and is now widely used in all walks of life in social production. A large part of the most common monitoring devices on the market are multi-function instruments, which are very common and have a large market share. Its implementation method is to connect all the collected parameters to a device through the secondary line. Its advantage is flexible installation and random installation. However, due to its random installation, it brings many secondary lines, troublesome wiring, uncontrollable process and inability to achieve standardized production, difficult maintenance and other disadvantages. Multiple cables are entangled with each other, which poses certain safety risks. In recent years, although some manufacturers have developed integrated intelligent switch components and made current, voltage and temperature acquisition into structured components, which has well solved the shortcomings brought by centralized monitoring, due to its changes in structural characteristics, the entire power distribution system needs to be 3C certified in actual use, which has a relatively large investment and high cost, and it is difficult to promote and apply it. In addition, the monitoring device is connected in series in the primary circuit, which increases the fault points of the circuit, easily leads to poor contact and low safety performance. Summary of the invention

[0003] The technical problem solved by the present invention is to provide an online monitoring module for a feeding circuit to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides an online monitoring module for a feeder circuit, comprising: a switch body, a monitoring device and a loop cable, wherein the monitoring device is fixed to the switch body by screws, and the monitoring device comprises: a monitoring device body, a monitoring device fixing part, a voltage indicator light, interfaces such as current sampling, a scrolling local display, a slide groove and a voltage and temperature collection guide column, wherein the monitoring device is fixed to the switch body by screws, the interfaces such as current sampling are arranged around the monitoring device body, and the voltage and temperature collection guide column is located in the slide groove.

[0005] Furthermore, the monitoring device fixing piece is provided with a circular hole for the temperature collection guide column to pass through.

[0006] Furthermore, the scrolling local display has horizontal and vertical structure modes.

[0007] Furthermore, the voltage and temperature collection guide pins can be moved to any position in the slide slot to ensure reliable contact.

[0008] Furthermore, the voltage and temperature collection guide column includes: a metal sheet, a compression spring, a power-taking copper column and a temperature sensor. The metal sheet is compressed and connected by the spring. The compression spring is located between the upper and lower metal sheets. The temperature sensor is embedded in the power-taking copper column.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the monitoring device is directly fixed on the switch body, realizing accurate collection of voltage and temperature, and there is no secondary line for voltage and temperature collection. The temperature collection is pre-buried in the conductor, and the collection accuracy is higher. Since it is directly hung on the switch body, the structure of the power distribution system is not changed. It can be adapted as long as there is a switch, with high flexibility and a wide trial range. The device has nothing to do with the primary cable, reducing the primary circuit fault point and improving safety. BRIEF DESCRIPTION OF THE DRAWINGS
