Abstract
The utility model relates to a commercial power socket and particularly relates to a safety socket with an earth leakage protection apparatus. The earth leakage protection apparatus and a socket body are arranged in a frame box body, and a power input end is connected to the socket body through the earth leakage protection apparatus. The socket body can be fixed by being embedded in a wall body or can be arranged to be movable, and an infrared indicating lamp HR is arranged on the socket body. The earth leakage protection apparatus and the socket are combined into one piece to ensure the normal operation of a power supply, electricity can be cut off automatically when short circuit, electric leakage and lightning stroke occur, and thus fire hazards and power failure are prevented.
Description
Technical field
The utility model relates to civil power socket, refers in particular to, with the safety socket of earth leakage protective device.
Background technology
Existing attaching plug, is keeping dormant state as air-conditioning, circuit, electric fan, computer etc. are inserted in socket, when thunderbolt, electric leakage, an electric fault and fire will occur, and has brought serious harm to personal family's property.Now widely used socket is not with safety guard, if load short circuits can cause the tripping operation of small size circuit, affects other power consumption equipment; Protecting the personal security of the lives and property and environmental protection and energy saving is our each scientific and technical personnel's obligations.
Summary of the invention
The purpose of this utility model is improved for the shortcoming existing in background technology and problem, provides a kind of simple in structure, and the safety socket with earth leakage protective device of standardization, mechanization production and installation is convenient in stable performance.
The technical solution of the utility model is structure a kind of electrified current transformer CT, contactor KM, the earth leakage protective device of dropout switch DZ and the safety socket that jack body is combined as a whole, wherein:
Described earth leakage protective device and jack body are arranged in same frame box body, and power input is connected to jack body through earth leakage protective device;
It is fixed on body of wall that described jack body is embedded in, or is set to movable socket, and jack body is provided with infrared indicator light HR.
The utility model has following advantage and effect:
The utility model by earth leakage protective device and socket be combined as a whole can protection power source normal work, and when being short-circuited, leaking electricity, being struck by lightning auto-breaking, thereby fire preventing and power-off.
Accompanying drawing explanation
Fig. 1 is the utility model electrical schematic diagram.
Fig. 2 is one of the utility model shape assumption diagram.
Fig. 3 is two of the utility model shape assumption diagram.
Embodiment
Known according to Fig. 1 to Fig. 3, the utility model comprises earth leakage protective device 1 and the jack body XS2 of electrified current transformer CT, contactor KM, dropout switch DZ, wherein:
Described earth leakage protective device 1 and jack body XS 2 are arranged in same frame box body, and power input is connected to jack body XS 2 through earth leakage protective device 1;
It is fixed on body of wall that described jack body 2 is embedded in, or is set to movable socket, and jack body XS2 is provided with infrared indicator light HR.
Described Current Transmit primary coil gets access to grid, and secondary coil is succeeded electrical equipment SH.
Described dropout switch DZ comprises solenoid TQ, and relay SH electrode connects tripping coil TQ, and tripping coil TQ senses that current-release switch DZ disconnects, and cuts off the electricity supply.
Principle of the present utility model, installation and use:
When electric leakage occurs in load, in CT, current phasor is non-vanishing, and relay SH electric shock adhesive is connected, and to tripping coil TQ, electric current is worked as in output, when size of current is enough in tripping coil, switch DZ is threaded off and disconnect, and cuts off the electricity supply.Common:
One, when when electric leakage occurs electric equipment, there are two kinds of anomalies: 1, the balance of electric current is destroyed, 2, voltage to earth appears in normal uncharged metal shell.
Two,, when abnormal generation, zero sequence current mutual inductor detects that current signal is abnormal through the current phasor of live wire and zero line and non-vanishing, has induction Voltage-output; The operation principle of current transformer and transformer ' s type seemingly, are comprised of two mutual coils on same iron core, and when primary coil has residual current, secondary coil will induce electric current.
Three, the primary coil of instrument transformer and the circuit of electrical network are connected, and secondary coil is received on the coil of relay SH, and the magnetic field that electric current produces makes the electrode adhesive in relay, regulates electric current simultaneously, and has connected external circuit.
Four, the electrode in relay SH is in the loop of tripping coil, and tripping coil TQ is a magnet spool, by electric current, produces attraction, and when size of current is enough, dropout switch DZ disconnects immediately, cuts off the electricity supply.
The utility model is comprised of framework, socket and the large parts of earth leakage protective device three; to make up the not defect with creepage protection function of the existing socket of China; framework is used for fixing socket and earth leakage protective device; be arranged on the support in wall; socket is the plug for connecting the household electrical appliances such as air-conditioning, electric furnace, electric fan, computer; earth leakage protective device can be protected the normal work of having led to power supply, and at irregular working auto-breaking when being short-circuited, leaking electricity, being struck by lightning, thereby fire preventing and power-off.
Embodiment described in the utility model is only the description that preferred implementation of the present utility model is carried out; not the utility model design and scope and method are limited; do not departing under the prerequisite of the utility model design philosophy; the various changes and modifications that in this area, engineering branch art personnel make the technical solution of the utility model; all should fall into protection range of the present utility model; the technology contents of protection described in the utility model, has all been documented in claims.
