Description
Technical field
The utility model relates to a kind of thunder-lightning device technology field, specifically a kind of T1 class surge protector.
Background technology
Surge protector is a kind of low-voltage variation device commonly used, and under normal circumstances, it is in high impedance status; in case and circuit is because of thunderbolt or other reasons when overvoltage occurring; its can conducting within the extremely short time, and overvoltage is introduced the earth by earth connection, comes equipment on protection circuit with this.When surge protector causes deterioratedly because of a variety of causes, this moment, surge protector can sharply generate heat, thereby made the trip gear action in surge protector, and surge protector and circuit are broken away from, and prevented the surge protector short circuit, and line accident is magnified.
T1 class surge protector of the prior art (wherein the T1 class is the I level classification test according to national Specification: put an electric current I, 1.2/50us surge voltage and 10/350us impulse current Iimp with nominal and test) has gas discharge type and two kinds of structures of spark gap type.
The structure of gas discharge type surge protector as shown in Figure 1a; in figure, 1a and 1b are two binding posts; wherein Reference numeral 2a is gas discharge tube; be filled with inert gas etc. in gas discharge tube; in the situation that without thunderbolt, gas discharge tube is in the state that opens circuit, when lightning strikes; affix thunderbolt voltage between two binding posts makes the inert gas in gas discharge tube can breakdown short circuit of moment.
Spark gap type surge protector structure is as shown in Fig. 1 b; 4a and 4b are respectively two electrodes of sparkover; in the absence of thunderbolt; gap between two electrodes does not have discharge spark; therefore be the state that disconnects, when lightning strikes, affix lightning voltage between binding post 3a and 3b; it is breakdown that the discharge spark of two electrodes makes the air in the gap, forms short circuit.
All there is following technological deficiency in the surge protector of above-mentioned two kinds of structures:
Unsteadiness due to air in the character of the inner inert gas of gas discharge tube itself and spark-discharge gap; be subject to the environmental impacts such as temperature, humidity, dust, other gases and air pressure; above-mentioned two kinds of surge protectors dispersiveness in discharge process is larger; action sensitivity is not enough; the general response time, the response time was slow more than 100ns.And, after discharge is completed, there is afterflow to exist, be unfavorable for the protection to alternating current, there is the not scissile problem of afterflow.
The utility model content
Technical problem to be solved in the utility model is that in prior art, there is the not scissile technical problem of insufficient sensitivity and afterflow in T1 class surge protector, thereby provides a kind of sensitivity higher and without the surge protector of afterflow.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of surge protector, the first binding post and the second binding post that comprise shell and be arranged at described enclosure both sides; Also comprise: bearing, be fixed in described outer casing bottom; Pressure cell is fixed on described bearing, and the first electrode tip of described pressure cell is connected with described the first binding post, and the second electrode tip of described pressure cell is connected with described the second binding post; Cross thermal trigger element, the inwall of its stiff end and described shell offsets, and the end of threading off is connected by low temperature scolding tin with described pressure cell the second electrode tip.
Also comprise removable triggering section and be fixed in the section that is triggered on described outer casing inner wall; Be provided with flexible member between described removable triggering section and described shell, described flexible member storage elastic potential energy under described thermal trigger element is excessively threaded off the conflict power effect of holding; After described dropout end was threaded off, described removable triggering section triggered the described section that is triggered under the effect of elastic potential energy.
Described flexible member is spring.
The described section of being triggered is electric switch, and it is electrically connected to external electromagnetic signal emission part.
Technique scheme of the present utility model has the following advantages compared to existing technology:
(1) surge protector described in the utility model, the first binding post and the second binding post that comprise shell and be arranged at described enclosure both sides; Also comprise: I class pressure cell, be fixed on bearing, the first electrode tip of described I class pressure cell is connected with described the first binding post, and the second electrode tip is connected with described the second binding post; Cross thermal trigger element, the inwall of its stiff end and described shell offsets, and the end of threading off is connected by low temperature scolding tin with described pressure cell the second electrode tip.Wherein use new technology, new technology; adopt high performance I class pressure cell; more than the highest continuous operating voltage of product can being accomplished 380V; safety applications is in the protection of L-N and the protection of front end L-PE; level of protection is low, and when thunderbolt without afterflow, move safer; reaction time is faster, less than 25nS.
(2) surge protector described in the utility model also comprises removable triggering section and the section that is triggered; Be provided with flexible member between described removable triggering section and described shell, described flexible member storage elastic potential energy under described thermal trigger element is excessively threaded off the conflict power effect of holding; After described dropout end was threaded off, described removable triggering section triggered the described section that is triggered under the effect of elastic potential energy.Therefore, after breaking down, cross thermal trigger element and carry out the action of threading off, the section of being triggered of just can setting out of the removable triggering section of being crossed then that thermal trigger element offsets can realize the fault remote signaling function, has higher coefficient of safety.
