Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Such as figure 1 As shown, a high-current over-temperature, over-voltage, and electromagnetic three-in-one tripping protector includes a water pipe 1 and an outer frame 2. The top of the outer wall of the water pipe 1 is provided with two branch pipes communicating with the water pipe 1. 3. The top of the two branch pipes 3 is provided with an outer frame 2, and the inside of the outer frame 2 is provided with an action slider 4 near the top. The left end of the action slider 4 is fixed on the outer frame 2 through a return spring 5, and the action slider 4 The bottom of the left end of the left end is provided with a small tooth 6 protruding downward, the outer wa...

Abstract

The invention relates to a high-current over-temperature, over-voltage and electromagnetic three-in-one tripping protector, which comprises a flowing water pipe and an outer frame. Two branch pipes communicated with the flowing water pipe are arranged on the top of the outer wall of the flowing water pipe. The outer frame is arranged on the tops of the two branch pipes. An operating sliding rod is arranged close to the top in the outer frame. A plurality of pressure springs are arranged on the outer wall of the operating sliding rod. A moving contact is arranged on the end part of each pressure spring. A plurality of fixed contacts opposite to the moving contacts are arranged in the outer frame. A fixing elastic piece and a bimetallic strip are arranged close to a left end at the inner bottom of the outer frame. The right end of the fixing elastic piece is connected with support shaft to which a lever is movably connected. A tripping coil is arranged above the right end of the lever. A pressure sensing device fixed in the branch pipe is arranged below the right end of the lever. An adjusting bolt fixed on the lever is supported above the right end of the bimetallic strip. The protector can work under a multi-contact high-current condition, temperature can be accurately and flexibly controlled, and the reliability of a product is improved.

Description

technical field [0001] The invention relates to a protector applied to an instant electric water heater, in particular to a three-in-one trip protector with large current overtemperature, overpressure and electromagnetic. Background technique [0002] The instant electric water heater of our country develops very fast at present, because the power of the instant electric water heater is all greatly higher than general electric water heater and other electrical appliances, its operating current reaches about 40A and power reaches 9KW and above. In a very limited heat exchange container, it is a feature of this type of product to use high power to exchange with water. Therefore, the instant electric water heater heats up very quickly when the system is abnormal, and the response speed of our protection device should also be very fast. At present, our conventional over-temperature protector is designed based on the traditional storage-type electric water heater. Its working cu...
