Abstract
The utility model relates to a leakage protective plug with ultrahigh temperature protection, belonging to the field of line connectors, and particularly relating to an electric plug with a protective device, composed of a plug and a leakage protection circuit. The utility model is composed of a mutual inductor, a trip coil, a thyristor shock absorption element and the leakage protection circuit, wherein, the leakage protection circuit is provided with a temperature control protection circuit. The utility model has the advantages that circuit design is simple, the function of a leakage protective plug is added, so that the phenomenon of fire which is caused by a burnt member of a leakage plug due to a contact failure between the plug and a socket plate can be prevented, and the safety of an electric appliance and an electric user can be protected.
Description
The leakage plug of the utility model band overtemperature prote belongs to the line connector field, particularly relates to a kind of plug that protective device is installed.
Existing leakage plug mainly is when electric leakage takes place, and plays and cuts off the electricity supply, the effect of protection electrical appliance; but in use, during owing to the loose contact between plug and the socket, the contact resistance between plug and the socket; meeting passing through because of electric current; produce very big heat, cause temperature to raise, can burn out the parts of leakage plug; make leakage plug lose defencive function; serious meeting is burnt, and causes fire, directly threatens electrical appliance and electric consumer's safety.
The purpose of this utility model is to avoid weak point of the prior art and a kind of leakage plug that has temperature protection is provided, and when the contact point temperature between plug and socket raises, in time cuts off the electricity supply protection electrical appliance and electric consumer's safety.
The purpose of this utility model reaches by following measure; existing leakage protecting plug is made up of plug and leakage protection circuit; it is by instrument transformer; tripping coil; impact-absorbing element, leakage protection circuit is formed, and it is on the basis of existing leakage protecting plug for the utility model; increase is protected temperature controlling, and the temperature control protection electric circuit is set in leakage protection circuit.When the loose contact between plug and the socket, the contact resistance between plug and the socket, meeting is passed through because of electric current, produces very big heat, and when causing temperature to raise, the temperature control protection electric circuit is in time cut off the electricity supply, protection electrical appliance and electric consumer's safety.Leakage protection circuit is to adopt temperature detect switch (TDS) is set in leakage protection circuit, also can adopt thermistor is set, and when bad, when causing temperature to raise, temperature detect switch (TDS) drives tripping coil circuit is disconnected the contact resistance between plug and socket because of contacting.
The utility model circuit design is simple, has increased the function of the conservative plug of electric leakage, prevents that because of the loose contact between plug and the socket parts that burn out leakage plug cause the phenomenon of fire, protection electrical appliance and electric consumer's safety.
