Description
Technical field
The present invention relates to for anti-electrical interference, particularly the general technology field of the protection equipment of the equipment of the anti-electrical interference that comes from the transient voltage surge and electric installation.
Prior art and shortcoming
The use of surge protection device (surge protection device) is known and common.Such equipment is usually with the guard block of rheostat as the reactance voltage surge.In fact, rheostat limits the surge of (clip) voltage based on predetermined value, and makes minimizing voltage surge spreading on feeder cable become possibility.
Such parts are deteriorated in its whole use procedure, and its resistance reduces gradually, so the strength increase of its leakage current, and therefore produce rheostatic remarkable heating by Joule effect.But this heating is transferred to contiguous equipment and fire hazard or short circuit.
Any possible deteriorated for fear of the equipment that is connected to this equipment or electric installation is necessary to make it possible to disconnect this equipment when rheostatic end-of-life.
The such off device that is called as thermal cutoff is to disconnect the rheostatic surge protection device of fault that comprises over the predetermined critical threshold temperature.
Therefore, file FR2848353 has described 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 (cord circuit), described cord circuit comprises the device for interruptive current, this device is removable between the off-position corresponding to the resting position of opening of circuit and circuit, and described interrupting device gets clogged during device is maintained in its closed position;
-being used 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, makes when reaching predetermined temperature, and active device produces the power that makes blocking device deexcitation (deactivate).Heat-sensing device is connected connect inseparably and formed by bimetal strip with active device.
Such equipment has shortcoming.In fact, open circuit and become possible activating element in view of it still makes, the bimetal strip that changes attribute during temperature raises stands high mechanical constraint.Such equipment becomes more unreliable at equipment after vibrated and impact.And the temperature detection of bimetal strip may be subject to the influence of peak current by thermal cutoff.Therefore, be necessary with checkout gear be sized to make electric current pass through not affect decoupler.
File FR2925216 has described a kind of surge protection device; it comprises surge protection parts and mechanical component; the surge protection parts be easy to that temperature-sensitive member according to its temperature deformation is connected, mechanical component is intended to cooperate with the temperature-sensitive member and can cooperates with the equipment that is used for triggering electric cut-out apparatus.
When the temperature of surge protection parts surpassed predetermined threshold, the distortion of temperature-sensitive member caused that housing comprises temperature-sensitive member and surge protection parts from the displacement of the outstanding mechanical component of housing, and the distortion of temperature-sensitive member activates the equipment that is used for triggering electric cut-out apparatus.
This surge protection device mechanically is connected with electric cut-out apparatus; therefore; have two housings, each has specific function: the critical functions obstacle temperature for detection of the surge protection parts, and another is used for being connected of remainder of disengagement failure protection equipment and electric installation.
The shortcoming of such equipment need to be used two housings for it, therefore causes the space waste of producing in cost and electric installation.And protection equipment and cut-out equipment are connected in current path.
Therefore, in these two patents, the solution requirement locking component is electric conductor, for example has the metal of mechanically known deformation performance, and requires it heat effect conversion can be become mechanical force.
And, it is also known that because for detection of rheostatic overheated functor from this rheostat too away from, therefore so surge protection device has the long thermal cutoff time, the reaction time of detecting overheated member is not that enough short the assurance disconnects fast.
