Description

Technical Field

[0001] This utility model relates to the field of solid-sealed pole technology, specifically a solid-sealed pole for a primary and secondary deep-integrated circuit breaker switch. Background Technology

[0002] A solid-insulated pole is an independent component that encapsulates a vacuum interrupter, conductive connections, and terminals with a solid insulating material. It uses the APG (Activated Particulate Gas) process to seal the vacuum interrupter and other conductive components into a single unit, completely isolating it from the external environment, enhancing insulation strength, and reducing damage to the interrupter and other conductive components from external conditions. Solid-insulated poles are widely used in indoor and outdoor vacuum circuit breakers. They are metal poles fixed to the circuit breaker body, and their function is to guide current to the external terminals through the internal insulation structure. The outer shell of the solid-insulated pole is generally made of copper or aluminum, and its surface requires special anti-corrosion treatment to ensure good conductivity and corrosion resistance under high-voltage conditions.

[0003] Based on this, according to the patent search, the announcement number CN218676923U discloses an integrated primary and secondary deep fusion insulation and solidification pole, which includes a pole body and a vacuum interrupter. The vacuum interrupter is set inside the pole body, which solves the problem of unreliable information transmission of circuit breaker feeder caused by weak wireless signal coverage in remote areas.

[0004] However, the above-mentioned practical application still has the following shortcomings: the structure of the traditional circuit breaker solid-sealed pole is simple. The outer shell of the solid-sealed pole is made of only aluminum metal and does not have a protective coating. When the circuit breaker is put into use, the solid-sealed pole is easily affected by factors such as external humidity, and the solid-sealed pole is prone to corrosion, which reduces the service life of the device.

[0005] To address the aforementioned issues, a solid-sealed pole for a circuit breaker switch with deep integration of primary and secondary circuits is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a solid-sealed pole for a primary and secondary deep-integrated circuit breaker switch. By using this device, the problems of traditional solid-sealed poles for circuit breakers being simple in structure, with the outer shell made of only aluminum metal without a protective coating, and the solid-sealed poles being easily corroded by factors such as external humidity when put into use, thus reducing the service life of the device, are solved.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a solid-sealed pole for a primary and secondary deep-integration circuit breaker switch, comprising a solid-sealed pole body, a main body shell disposed on the outer periphery of the solid-sealed pole body, an insulating layer disposed on one side of the main body shell, a flame-retardant layer disposed on the outer side of the insulating layer, and a waterproof layer disposed on the outermost side of the main body shell; the main body shell is a component made of stainless steel, the insulating layer is a component made of epoxy resin coating, and the flame-retardant layer is a component made of rubber insulating coating; a vacuum interrupting chamber is disposed inside the solid-sealed pole body, an outgoing line side chamber is disposed on one side of the solid-sealed pole body, a current sensor and a voltage sensor are disposed inside the outgoing line side chamber, and a conductive rod is disposed on one side of the solid-sealed pole body, with one end of the conductive rod extending into the vacuum interrupting chamber.

[0008] Preferably, one end of the conductive rod is provided with an outgoing terminal, and the upper end of the solidified pole body is provided with an incoming terminal.

[0009] Preferably, a temperature sensor is provided at the end of the conductive rod away from the output terminal, and the temperature sensor is located inside the solid-sealed pole body.

[0010] Preferably, the voltage sensor is electrically connected to both the input terminal and the output terminal.

[0011] Preferably, an anti-corrosion layer is provided between the flame-retardant layer and the waterproof layer.

[0012] Preferably, the anti-corrosion layer is a component made of copper metal, and the waterproof layer is a component made of silicone conformal coating.

[0014] 1. This utility model discloses a solid-sealed pole for a primary and secondary deep-integration circuit breaker switch. The main body shell is made of stainless steel; the insulation layer is a protective layer made of epoxy resin coating, which has good mechanical and insulating properties. Environmentally friendly epoxy resin coating is used for heat-sensitive substrates and corrosion protection, improving the stability, corrosion resistance, and chemical resistance of the main body shell; the flame-retardant layer is a protective layer made of rubber insulating coating, which is composed of special silicone rubber combined with other polymers and high-performance materials, often used in electrical equipment. Its non-flammable properties enhance the flame-retardant effect of the main body shell; the anti-corrosion layer is a copper plating layer, mainly used to improve the conductivity and corrosion resistance of the solid-sealed pole body, giving the solid-sealed pole body good conductivity and ensuring the solid-sealed pole... The surface of the main body of the solid-sealed pole is protected from environmental and chemical corrosion. The waterproof layer is the outermost layer of the solid-sealed pole body, which is a protective layer made of silicone conformal coating. The silicone conformal coating has comprehensive protective properties such as waterproofing, moisture-proofing, dustproofing, and corrosion resistance, giving the solid-sealed pole body high temperature resistance and high chemical stability. It can effectively isolate the circuit board in the solid-sealed pole body from the corrosion of the external environment. The silicone conformal coating can be applied by brushing, spraying, dipping, and other processes, and has a fast curing speed. This design, by adding multiple protective layers to the outer circumference of the main body shell, extends the service life of the main body shell and improves the safety of the solid-sealed pole body.

The digital display screen shows the temperature, current, and voltage data. The design of the monitoring mechanism allows staff to easily monitor the sealed pole body, thereby ensuring the safety of the sealed pole body and the circuit breaker switch.
