Description

Technical Field

[0001] The present invention relates to a relay protection device, in particular to a relay protection device with a high waterproof and dustproof grade. Background Art

[0002] Most of my country's eastern coastal areas have a subtropical monsoon climate with abundant rainfall. The original distribution room did not have ventilation and dehumidification equipment such as air conditioners and dehumidifiers. The operating environment was relatively harsh and condensation was easily formed indoors.

[0003] Currently, the most common installation method for relay protection devices is to use a metal casing and fix it with a rear cover. The protection level is usually IP40 for the front panel, IP30 for the side of the box, and IP20 for the rear panel. The protection level is relatively low and cannot be waterproof or dustproof.

[0004] Therefore, there is an urgent need for a relay protection device with a simple structure, heat and humidity resistance, effective adaptation to various harsh working environments, and high waterproof and dustproof level. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a new relay protection device.

[0006] The first aspect of the present invention provides a relay protection device, comprising: a shell, the shell being made of an integral aluminum profile and formed by hot extrusion, constituting the top plate, bottom plate and two side plates of the relay protection device, a front panel fixed to the front end opening of the shell, and a rear panel fixed to the rear end opening of the shell, the interior of the cavity surrounded by the shell, the front panel and the rear panel being filled with silicone rubber as a whole.

[0007] In the relay protection device provided by the second aspect of the present invention, the LCD screen and buttons are eliminated from the front panel, and only indicator lights are provided.

[0008] In the relay protection device provided by the third aspect of the present invention, the silicone rubber can maintain elasticity within a temperature range of -60°C to 200°C.

[0009] In the relay protection device provided in the fourth aspect of the present invention, the silicone rubber has a voltage resistance of more than 10,000V.

[0010] In the relay protection device provided in the fifth aspect of the present invention, the protection grade of the relay protection device is above IP65.

[0011] The relay protection device of the present invention improves the overall protection level of the relay protection device by improving the processing technology and the glue filling technology of the shell, and optimizes the waterproof and dustproof properties of the relay protection device. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a side view of the relay protection device of the present invention.

[0013] Figure 2 It is a front view of the relay protection device of the present invention. DETAILED DESCRIPTION

[0014] In order to explain the present invention in more detail, the following describes the mode for implementing the present invention with reference to the accompanying drawings. In the accompanying drawings, the same or corresponding reference numerals are used to represent the same or corresponding technical features.

[0015] Figure 1 It is a side view of the relay protection device of the present invention.

[0016] like Figure 1 As shown, the relay protection device 100 of the present invention is roughly cubic in shape. Its housing 101 is formed from a one-piece aluminum profile by hot extrusion. The housing 101 forms the top, bottom, and side panels of the relay protection device 100 of the present invention. Due to the integrated molding process, there are no gaps between the top, bottom, and side panels. Furthermore, the aluminum profile makes the housing corrosion-resistant and resistant to oxidation.

[0017] The front opening of the housing 101 is provided with a front panel 102, and the rear opening is provided with a rear panel 103. The front panel 102 and rear panel 103 can be fixed to the housing 101 by various means, including but not limited to screwing, riveting, welding, etc. The rear panel 103 is provided with connection terminals 104 for connecting to external cables.

[0018] In the present invention, the interior of the cavity surrounded by the housing 101, the front panel 102 and the rear panel 103 is entirely filled with silicone rubber 105 for sealing to prevent moisture and dust from entering, and to provide long-term protection for internal electronic components, forming an effective barrier to prevent environmental pollution.

[0019] Figure 2 It is a front view of the relay protection device of the present invention.

[0020] like Figure 2 As shown, on the front panel 102, the LCD screen and buttons are cancelled, and only the indicator light 106 is set to reduce gaps and exposed parts, further improving the protection level. Of course, as those skilled in the art can understand, the indicator light 106 is also cancelable.

[0021] The present invention improves the overall protection level of the relay protection device 100 and optimizes the waterproof and dustproof properties of the relay protection device 100 by improving the processing technology and the glue-filling technology of the housing 101 of the relay protection device 100 .

[0022] To ensure the protection level of the relay protection device 100, the interior of the relay protection device 100 is sealed with silicone rubber using a potting process. Silicone rubber exhibits strong aging resistance, excellent weather resistance, and excellent impact resistance. It is resistant to thermal shock and has excellent thermal conductivity. It maintains elasticity and resists cracking within a temperature range of -60°C to 200°C. It also exhibits strong electrical properties and insulation, surpassing epoxy resin in insulation performance and capable of withstanding voltages exceeding 10,000V. Its excellent thermal conductivity and flame retardancy effectively enhance the heat dissipation and safety factor of electronic components. It also has low viscosity and good fluidity, minimal curing shrinkage, and strong waterproof and shock resistance, making it suitable for potting electronic components operating in harsh environments.

[0023] This relay protection device is resistant to moisture and heat, and has a high protection level of IP65, making it suitable for various harsh working environments.
