Description

Technical Field

[0001] This utility model belongs to the technical field of maintenance of electrostatic precipitator equipment in non-stop mode, specifically relating to a wiring device for cathode suspension and high-voltage through-wall insulator of electrostatic precipitator. Background Technology

[0002] The electrostatic precipitator in the sulfuric acid workshop is a horizontal single-chamber four-field type. Each electrostatic precipitator is equipped with a transformer and a high-voltage disconnect switch on the top. The high-voltage disconnect switch is connected to the cathode hanging inside the electrostatic precipitator using cables and high-voltage wall insulators. This connection must be insulated from the outer shell of the electrostatic precipitator, otherwise the equipment will not be able to operate normally.

[0003] During use, the high-voltage wall-penetrating insulators in the electric field near the front of the two electrostatic precipitators are prone to damage. The high-voltage wall-penetrating insulators on one side of the electric field are installed vertically downwards and partially embedded inside the electrostatic precipitator. The bottom terminals of the high-voltage wall-penetrating insulators are connected to the cathode hanging terminals in the electric field by cables. When the cables are damaged, the temperature inside the electric field is high, and the operators cannot enter the electric field to work. The power must be turned off and the temperature must be lowered before the operators can enter the electric field to handle the problem. Replacement cannot be performed within the normal production cycle. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems and provide a wiring device for the cathode suspension of an electrostatic precipitator and the high-voltage through-wall insulator.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A wiring device for cathode hanging and high-voltage through-wall insulator of electrostatic precipitator is disclosed. The wiring device is a metal flat strip with a bent section in the middle, making it into a '<' shape. The two ends of the metal flat strip are bent to form a first connecting part and a second connecting part, respectively. A first connecting screw hole is opened on the first connecting part and a second connecting screw hole is opened on the second connecting part.

[0007] Furthermore, the length of the metal flat strip is greater than the distance between the high-voltage through-wall insulator and the cathode suspension terminal.

[0008] Furthermore, a sleeve is fitted over the metal flat strip, and the sleeve is fixed to the cathode hanger by fixing screws.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model uses metal flat strips to replace flexible cables. By utilizing the rigidity and elasticity of the metal flat strips, it overcomes the defects of flexible cables that are difficult to install. It can also better adapt to the distance between the high-voltage wall insulator and the cathode hanging terminal, greatly reducing the difficulty of operation and improving work efficiency.

[0011] 2. This utility model eliminates the need for operators to enter the electric field, thus avoiding operational risks and potential losses due to power outages.

[0012] 3. The metal flat strip of this utility model is provided with a sleeve on the outside, which can solve the problem of loose connection caused by high frequency vibration;

[0013] 4. This utility model has a simple structure, is easy to operate, and has low cost. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings. Example

[0020] like Figure 2-3As shown, a wiring device for connecting the cathode hanger and the high-voltage through-wall insulator of an electrostatic precipitator is disclosed. The wiring device is a metal flat strip, the length of which is greater than the distance between the terminals of the high-voltage through-wall insulator 6 and the cathode hanger 9. The metal flat strip has a bent section 3 in the middle, making it have an overall '<' shaped structure. The rigidity and elasticity of the metal flat strip can better adapt to the distance between the terminals of the high-voltage through-wall insulator 6 and the cathode hanger 9. The two ends of the metal flat strip are bent to form a horizontal first connecting part 1 and a second connecting part 2, respectively. The first connecting part 1 has a first connecting screw hole 4, and the second connecting part 2 has a second connecting screw hole 5. A sleeve 10 is fitted on the outside of the metal flat strip, and the sleeve 10 is fixed to the cathode hanger 9 by fixing screws 11.

[0021] When replacing the wiring device, the operator stands outside the electric field with tools in hand, inserts the tools through the inspection hole, aligns them with the terminals of the high-voltage through-wall insulator 6 and the cathode hanger 9, unscrews the corresponding bolts, and then puts the sleeve 10 onto the cathode hanger 9. Figure 2 As shown, place the prepared metal flat strip wiring device on the tool and insert it using the tool. First, place the second connecting part 2 on the terminal block of the cathode hanger 9, align the second connecting screw hole 5 with the second connecting screw hole 8 and tighten it. Then, use the tool to move the first connecting part 1 of the metal flat strip, align the first connecting screw hole 4 with the first connecting bolt 7 on the high-voltage through-wall insulator 6 and tighten it. Then, use the tool to move the sleeve 10 upward and fit it around the metal flat strip, and use the fixing screw 11 to fix the sleeve 10 on the cathode hanger 9. The replacement operation is now complete.
