Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of voltage collection, especially to a groove voltage collection wiring terminal box. BACKGROUND

[0002] In the production process of electrolytic cell, the collection of groove voltage is crucial for monitoring the running state of electrolytic cell. The accurate collection of groove voltage can not only help the operator to understand the working state of electrolytic cell in real time, but also provide an important basis for the optimization and fault diagnosis of the production process. Therefore, as the key equipment connecting electrolytic cell and voltage collection module, the performance and reliability of the groove voltage collection wiring terminal box of electrolytic cell directly affect the stability and efficiency of the whole electrolytic production system.

[0003] At present, the wiring mode of the groove voltage collection wiring terminal box of electrolytic cell mainly adopts the traditional cable introduction and outgoing mode. Specifically, the cable at the end of electrolytic cell frame is introduced into the wiring terminal box, and the outgoing electrolytic cell ion membrane collection cable is connected to the wiring terminal box. In addition to the two lines at the head and tail of the groove, the middle cable is a public cable. However, in the existing wiring mode, the middle public cable of the electrolytic cell ion membrane collection cable is directly short-circuited on the voltage collection module. This design leads to the fact that when a break occurs in the middle of the voltage collection cable, the break cannot be detected. Because when the break occurs, the voltage signal is still transmitted through the short-circuited public cable, so the actual state of the cable cannot be identified, and the cable fault cannot be found in time.

[0004] In view of the problems in the related art, the utility model provides a groove voltage collection wiring terminal box. UTILITY MODEL CONTENTS

[0005] The utility model aims at the defects of the prior art, and provides a groove voltage collection wiring terminal box, which can effectively detect the break problem of voltage collection cable, improve the accuracy and reliability of voltage collection, simplify the maintenance process, and reduce the difficulty of troubleshooting.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0012] Further, the terminals 2-56 in the first terminal row are connected with the terminals 2-56 in the second terminal row through shorting wires.

[0013] Further, the terminals 1-56 in the first terminal row are connected with a voltage signal acquisition module; and the terminals 2-57 in the second terminal row are connected with the voltage signal acquisition module.

[0014] Further, the shorting wires are low-resistance wires.

[0015] Further, a protection device is arranged in the cabinet.

[0016] Further, the cabinet has a size of 550mm*250mm*700mm, and the mounting plate has a size of 500mm*650mm.

This design not only improves the accuracy and reliability of voltage acquisition, but also simplifies the maintenance process, reduces the troubleshooting difficulty, and improves the safety and stability of the entire electrolytic cell voltage acquisition system.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] The purpose of the present application is to provide a tank voltage acquisition wiring terminal cabinet for the defects of the prior art.

[0024] EMBODIMENT

[0025] The present embodiment provides a tank voltage acquisition wiring terminal cabinet, as shown in the drawings, comprising a cabinet 1 and a mounting plate 2 mounted in the cabinet 1. Figures 1-4

[0026] The length, width and height of the cabinet 1 are 550mm x 250mm x 700mm, and the size of the mounting plate 2 is 500mm x 650mm. The cabinet 1 is made of metal material, and the surface is treated by corrosion protection to adapt to the humid environment of the electrolytic tank workshop. The mounting plate 2 is fixed inside the cabinet 1 and used for mounting terminal blocks and other electrical elements.

[0027] Two rows of terminal blocks are mounted on the mounting plate 2, which are a first terminal block TB-F1 and a second terminal block TB-F2. The TB-F1 contains 56 terminals, and the TB-F2 contains 57 terminals. The TB-F1 and the TB-F2 are both fuse wiring terminals, which can effectively protect the circuit from damage caused by overload and short circuit.

[0028] The TB-F1 can be used as a field side electrolytic tank voltage acquisition cable introduction end, and is connected to the positive electrode of the electrolytic tank voltage acquisition cable. The terminal 1 of the TB-F1 is used to connect the tank head cable 1-EA of the electrolytic tank voltage acquisition cable, and the terminals 2-56 of the TB-F1 are respectively used to connect the electrolytic tank voltage acquisition cable 1-B01-1-B55.

[0029] The TB-F2 is used to connect the negative electrode of the field side electrolytic tank voltage acquisition cable. The terminal 57 of the TB-F2 is used to connect the tank tail cable 1-EC of the electrolytic tank voltage acquisition cable. ​

[0030] The fuse link terminals between TB-F1 and TB-F2 are connected by shorting wires 3, which are low-resistance wires; however, the terminal 1 (slot head cable) of TB-F1 and the terminal 57 (slot tail cable) of TB-F2 are not shorted. The specific shorting method is as follows:

[0031] The terminals 2-56 of TB-F1 are respectively connected to the terminals 2-56 of TB-F2 by shorting wires 3. This wiring method avoids the shorting process of the intermediate common cable on the voltage signal acquisition module, thereby effectively detecting the broken cable problem.

[0032] In this embodiment, the voltage signal acquisition module is installed outside the wiring terminal box on the field side. Its specific position can be set according to the actual situation, and its implementation method can refer to the prior art. This embodiment will not be described in more detail.

[0033] The terminals 1, 2-56 of TB-F1 serve as the positive pole of the slot voltage signal, and the terminals 2-56, 57 of TB-F2 serve as the negative pole of the slot voltage signal, which are respectively connected to the voltage signal acquisition module. The voltage signal acquisition module detects the voltage signal between TB-F1 and TB-F2 to determine whether the electrolytic tank voltage acquisition cable is broken. When a certain segment of the voltage signal is detected to be 0, it can be determined that the corresponding cable is broken.

[0034] In order to protect the first terminal row TB-F1, the second terminal row TB-F2 and the shorting wires 3 from external interference, a protection device is provided in the cabinet 1. The protection device is made of insulating material, which can prevent dust, moisture and accidental touch from affecting the terminal row and the shorting wires, thereby improving the stability and reliability of the system.

[0035] The wiring method of this embodiment allows the electrolytic tank voltage acquisition cable to be connected to the wiring terminal box, with the positive and negative voltage signal cables separated and independent, avoiding the shorting process of the intermediate common cable on the remote station voltage acquisition module. When the voltage acquisition cable is broken, the voltage acquisition module can directly detect the fault point. Maintenance personnel can quickly locate the faulty cable according to the alarm signal for repair. This design greatly simplifies the maintenance process, reduces the difficulty of troubleshooting, and improves the maintenance efficiency of the system.

[0036] It should be noted that the above only the preferred embodiments of the present application and the use of technical principles. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, those skilled in the art can make various obvious changes, re-adjustment and replacement without departing from the scope of the present application. Therefore, although the above embodiments of the present application has been described in more detail, but the present application is not limited to the above examples, without departing from the concept of the present application, but also can include more other equivalent embodiments, and the scope of the present application is determined by the appended claims.
