Pressure switch detecting device for transformer multifunctional protector

The utility model provides a pressure switch detecting device for a transformer multifunctional protector, which comprises a bearing body, a bracket, an air inlet, an air outlet, and a pressure gauge. The device is characterized in that the bearing body is in the shape of a circular cylinder. The centers of the two end covers of the circular cylinder are provided with an air inlet and an air outlet respectively. The air inlet is composed of a quick coupling and a ball valve switch. The pressure gauge, an indicating lamp and a pressure switch tube mounting base are sequentially arranged at the upper side of the bearing body. The indicating lamp is internally provided with a battery, and is externally provided with a wiring clip. The indicating lamp, the battery and the wiring clip form an open circuit. According to the technical scheme of the utility model, the bearing body is in the shape of the circular cylinder, so that the pressure is uniformly distributed on the sidewall of the bearing body. Therefore, the compressive strength of the bearing body is increased, and both the airtightness and the safety of the device are improved. The pressure gauge and the indicating lamp facilitate the observation. The device is simple in structure, and the cost is greatly reduced. The device greatly facilitates the operation for non-professional pressure switch manufacturers. The device is convenient in operation and greatly increases the operating efficiency.
