Description

Earth leakage circuit breaker

Technical field

This utility model is related to electric leakage protection technology field, specifically a kind of earth leakage circuit breaker.

Background technology

Chopper is the important electric elements in controller switching equipment, and chopper can be used to distribute electric energy, infrequently start different Step motor, carries out to power circuit and motor etc. and protects, when they occur serious overloads or short-circuit and under-voltage wait event Energy automatic shutdown circuit during barrier, its function is equivalent to Fuse switch and the combination for crossing underheat relay etc..And in disjunction Parts need not be changed as fault current is latter；At present, obtain a wide range of applications.

Jing often has similar following situation in daily life：Earth leakage protective device is provided with electric heater under normal circumstances, The earth leakage protective wall namely declared in advertisement, just because of this, many people are the electric heaters when burning, although set reaching It is no longer heat up when constant temperature is spent, what main power was also to turn on, though earth leakage protective wall can play safety to a great extent and prevent Model is acted on, but not perfectly safe；Again or cold water pipe run out sometimes, the water of hot-water line is also flowing out, using dangerous；Again Exactly there may come a time when can operational error, by cold water pipe mistake be screwed to hot-water line this, make hot-water line always in flowing water, no The energy is only wasted, electric leakage risk is also had.

Therefore sometimes to be perfectly safe, need it is manual pulls up plug, after a bath after plug again, although thoroughly prevent Potential safety hazard, but it is cumbersome to operate, it will usually there is situation about forgetting, be not to forget to pull up exactly to forget after use Plug.

Utility model content

This utility model overcomes the deficiency in the presence of above-mentioned prior art, there is provided a kind of rational in infrastructure, by stream Measure to control to automatically open up or cut off the earth leakage circuit breaker of main switch.

What the technical solution of the utility model was realized in：

A kind of earth leakage circuit breaker, including：

Zero sequence current mutual inductor, which is connected between master switch and load, whether there is drain conditions for detecting on circuit；

Flow sensing circuit, is connected with electronic amplification circuit, for detect rate-of flow and flow exceed setting value when Trigger is sent, and then leakage tripping device is controlled.

Preferably, described flow sensing circuit is flow transducer.

Preferably, described flow transducer is used for water heater, and flow transducer is arranged on the hot water of water heater and goes out At mouthful.It is possible thereby to ensure that using for water heater is safe to a certain extent.

For convenience flow is set, preferably, also include the threshold value being connected with flow sensing circuit arranging Module, for arranging flow threshold.

Setting time for convenience, preferably, wireless communication module and intelligent terminal are also included, described flow inspection Slowdown monitoring circuit is wirelessly connected with intelligent terminal by wireless communication module.Wireless setting can be carried out by intelligent terminal, conveniently again Fast.

Preferably, described wireless communication module is bluetooth module or WIFI module.

Preferably, described intelligent terminal be smart mobile phone, panel computer, any one in PC or VR equipment.

Preferably, also including wireless router, described wireless module connects outer net and intelligence by wireless router Terminal.Thus, it is possible to pass through remotely to be controlled, water heater even load is allow to close or open according to the time of remote setting Open.

Preferably, described flow sensing circuit includes display screen and button.Can also be straight in water heater even load Tap into capable operation.

Preferably, described threshold setting module includes display screen and button.

Preferably, described temperature sensing circuit is connected with electronic amplification circuit by microprocessor.

The principle of the present utility model and beneficial effect for employing above-mentioned technical proposal be：

Flow of this utility model by real-time detection medium such as water, when rate-of flow is more than setting value, flow inspection Slowdown monitoring circuit provides flow exceeded signal to electronic amplification circuit, and electronic amplification circuit sends operational order to leakage tripping device, leaks Electrical circuit breakers master switch automatically cuts off power supply.

The technical solution of the utility model is employed, the use water heater even load that user can be safer was both square Use, reached energy-saving effect again.
