Description

Technical Field

[0001] The utility model relates to a power supply disk, in particular to a power supply disk suitable for use in high temperature environments. Background Art

[0002] The 220V power supply panel is composed of a leakage protection switch (32A), a thermal protection switch (60℃), and a 3*4mm² rubber-plastic cable. The thermal protection switch is a thermostat with a bimetallic temperature-sensing component. It is connected in series in the circuit during normal operation and is in a closed state. When the temperature reaches the action temperature, the metal sheet is heated, generating internal stress and quickly acting to disconnect the main circuit. The current leakage protection switch is an integrated leakage protection switch with electromagnetic release and thermal release. When it is usually used in a high temperature environment (ambient temperature ≥50℃), the thermal protection of the power supply panel will be frequently actuated, which cannot meet the normal working requirements under high temperature conditions.

[0017] like Figure 1 As shown, a power supply panel suitable for use in a high temperature environment includes a leakage protection switch, a thermal protection switch 1, an aluminum foil thermal insulation film 2, and a thermal insulation board 3, wherein the leakage protection switch uses an electromagnetic residual current operated circuit breaker as a main switch control circuit. The thermal protection switch 1 is connected in series in the circuit, and the thermal protection switch 1 is arranged in a thermal insulation box.

[0018] The upper end of the thermal protection switch 1 is provided with a reset button 5, which passes through the heat insulation box and extends out of the heat insulation box. The lower end of the reset button 5 is provided with a wiring terminal, which is connected in series in the circuit through the wiring terminal.
