Description

Technical Field

[0001] The utility model belongs to the technical field of cooling water for phase shifters, in particular to an ion exchange resin replacement device for cooling water for phase shifters. Background Art

[0002] Double-water internally cooled phase shifters require constant replenishment of stator and rotor cooling water with qualified conductivity as a cooling medium. Increased conductivity of the stator and rotor cooling water can lead to reduced insulation performance, discharge, and other issues, impacting the normal operation of the phase shifter. Increased conductivity of the stator and rotor cooling water typically requires replacement of the ion exchange resin in the water treatment unit. Currently, replacing ion exchange resins is primarily performed manually, using the resin addition port. Due to the small diameter of the resin addition port, resin fluidity is reduced, so a funnel is often inserted into the port and a tamping rod is used to add resin. This method is time-consuming and can damage resin particles during use, impacting resin performance.

[0003] In the patent "A resin adding device for a phase-shifting ion exchanger, patent number: CN202021817896.X", manual loading is improved to an automatic loading mode, but in principle, the resin is still added to the resin tank through the external force of the feeding rod, and there is a possibility that the resin will be damaged by external friction in the device.

[0004] The patented "Resin Replacement Device for Converter Station Water Systems Based on Negative Pressure Jetting" (Patent No.: CN202122663321.8) improves the resin addition method by employing a jet-based method, preventing damage to the resin from external mechanical forces during addition. However, due to the high viscosity of the resin particles, the ejector's slow resin delivery speed failed to significantly improve work efficiency.

[0005] The patent, "An Integrated Cooling Water Resin Replacement and Hydrostatic Testing Device (Patent No.: CN202322631890.3), adds a hydrostatic testing function to the resin addition principle using a jet. However, it does not address the slow resin delivery speed of the jet.

[0006] In addition, the existing resin addition method has the following factors in actual application that affect on-site work efficiency:

[0007] 1) Currently, the stator and rotor water systems of condenser phase converters all require resin treatment. This resin replacement is done manually, with approximately 300 kg of resin required for each replacement per machine and system. Due to the integrated design of condenser phase converter equipment, the resin tank is located high. This results in issues such as a high resin injection port, a low outflow port, and a narrow injection port diameter, making manual replacement inefficient. However, the technical difficulty of replacement is relatively low.

[0008] 2) Since the resin must be stored away from light, each manual replacement requires manual handling. Due to the large amount of resin and its heavy weight, there are safety hazards such as injuries during handling. Resin replacement requires climbing, and if the resin comes into direct contact with the skin or eyes, there is a risk of chemical corrosion. Utility Model Content
