Description
Technical field
The present invention relates to for anti-electrical interference, particularly the anti-general technology field coming from the equipment of the electrical interference of transient voltage surge and the proterctive equipment of electric installation.
Prior art and shortcoming
The use of surge protection device (surgeprotectiondevice) is known and common.Rheostat is used as the guard block of reactance voltage surge by such equipment usually.In fact, rheostat based on predetermined value restriction (clip) voltage surge, and makes minimizing voltage surge spreading on feeder cable become possibility.
Such parts are deterioration in its whole use procedure, and its resistance reduces gradually, and therefore the intensity of its leakage current increases, and is therefore produced rheostatic remarkable heating by Joule effect.This heating is transferred to contiguous equipment and can fire hazard or short circuit.
In order to avoid being connected to the deterioration of the equipment of this equipment or any possible of electric installation, be necessary to make it possible to disconnect this equipment when rheostatic end-of-life.
The such off device being called as thermal cutoff is to disconnect and comprises the rheostatic surge protection device of the fault exceeding predetermined critical threshold temperature.
Therefore, file FR2848353 describes a kind of equipment for the protection of the surge of electrical equipment reactance voltage, and this equipment comprises:
-protected location, it is connected to electrical equipment via cord circuit (cordcircuit), described cord circuit comprises the device for interruptive current, this device is corresponding to removable between the resting position opened of circuit and the off-position of circuit, and described interrupting device gets clogged during device is maintained in its closed position;
-for opening the device of cord circuit when the temperature of protected location has reached predetermined value, it comprises heat sensitive device.This heat-sensing device is connected to active device, and make when reaching predetermined temperature, active device produces the power making blocking device deexcitation (deactivate).Heat-sensing device is connected inseparably with active device and is formed by bimetal strip.
Such equipment has shortcoming.In fact, in view of it still makes to open the activating element that circuit becomes possible, the bimetal strip changing attribute during temperature raises stands high mechanical constraint.Such equipment equipment through vibrated and impact after become more unreliable.And the temperature detection of bimetal strip may be subject to the impact of the electric current by thermal cutoff.Therefore, be necessary checkout gear to be sized to make electric current by not affecting decoupler.
File FR2925216 describes a kind of surge protection device; it comprises surge protection parts and mechanical component; surge protection parts be easy to be connected according to the heat sensitive member of its temperature deformation, mechanical component is intended to cooperate with heat sensitive member and can cooperates with the equipment cutting off apparatus for activating electrical.
When the temperature of surge protection parts exceedes predetermined threshold, the distortion of heat sensitive member causes the displacement of the mechanical component given prominence to from housing, housing to comprise heat sensitive member and surge protection parts, and the distortion of heat sensitive member activates the equipment being used for activating electrical cut-out apparatus.
This surge protection device with electrically cut off apparatus and be mechanically connected; therefore; there are two housings, each have specific function: one for detecting the critical functions obstacle temperature of surge protection parts, and another is for the connection of the remainder of disengagement failure proterctive equipment and electric installation.
The shortcoming of such equipment needs use two housings for it, therefore causes the space waste produced in cost and electric installation.And proterctive equipment and cut-out equipment are series connection in current path.
Therefore, in these two patents, solution requirement locking component is electric conductor, such as, have the metal of mechanically known deformation performance, and requires that heat effect conversion can be become mechanical force by it.
And, it is also known that because for detect rheostatic overheated functor from this rheostat too away from, so surge protection device has the long thermal cutoff time, therefore the reaction time detecting overheated component be not that enough short guarantee disconnects fast.
