State display panel has one end connected with the thermal fuse (low-temperature welding sheet), and the other end connected with the casing via tension spring. The module further includes a thermo-sensitive device disposed on the thermistor valve element. Two poles of the thermo-sensitive device extend out of the casing via output terminals. The base includes an electrically connected input terminal and an output terminal, and the input terminal is corresponding to the output terminal of the thermo-sensitive device of the module. The inventive surge protector is safer than existing surge protector, can meet branching requirement for safety and reliability of special system, and has functional interface capable of being connected with microcomputer monitoring system of modern electrical system.
Description
Technical field
The utility model relates to a kind of surge protector.
Background technology
Existing surge protector mainly is made up of module and base two parts.Module section mainly is made up of thermistor valve block, thermal cut-off and overcurrent protector; this structure can only make the surge protector module at the performance degradation of the thermistor valve block of overcurrent and interior dress to degree considerably beyond each professional system of China (comprising railway, public security, post and telecommunications etc.) standard; could show and break away from protected equipment; and the temperature of thermistor valve block under the situation of earial drainage and performance degradation can be very high; as can not in time obtaining monitoring and changing, can cause potential safety hazard.Even there is portioned product to consider the serviceability temperature device, but also only be realize the thermistor valve block when performance degradation demonstration and break away from the function of protected equipment.Can't use microcomputer monitoring mode in the modern electrical system to eliminate the potential safety hazard of surge protector; that is: the operating state of precise monitoring surge protector---write down its effective conducting number of times and when its performance exceeds standard but be not badly damaged, carry out early warning, even so that change by microsystem.The major function of base portion is an installed module, and portioned product is provided with the switch of reporting to the police when thermal cut-off in the module or the fusing of temperature device.This structure can't realize and being connected of microcomputer detecting system, also can't reach the separated time requirement in the professional system.
Summary of the invention
The purpose of this utility model is to solve the problem of above-mentioned existence; thoroughly eliminate safe hidden trouble, provide a kind of than existing surge protector safer, can adapt to that the safe and reliable separated time of professional system requires, as to have the functional interface that can be connected novel surge protector with the microcomputer detecting system of modern electrical system.
The technical scheme that the utility model adopted is; surge protector; comprise module and base; the middle part that described module is included in housing is provided with the thermistor valve block, the direct connection electrode of an end of described thermistor valve block, connection electrode after the other end is connected with thermal cut-off and overcurrent protector; status display panel one end is that the low temperature weld tabs is connected with thermal cut-off; be connected by extension spring between the other end and the shell, it is characterized in that
Described module further comprises a temperature-sensitive device, and described temperature-sensitive device is arranged on the thermistor valve block, and housing is stretched out by output in the two poles of the earth of described temperature-sensitive device;
Described base comprises the access terminal and the lead-out terminal of electrical connection, the temperature-sensitive device output of the corresponding described module of described access terminal.
Adopt the surge protector of said structure, can monitor in real time, eliminated the potential safety hazard that under running status beyond target, produces fully its operating state.In addition, the base of novel band separated time function can solve the separated time problem for the professional system that this requirement is arranged.

Embodiment
Surge protector of the present utility model comprises that equally module 10 and base 20 two parts form, and wherein Fig. 1,2 has illustrated the structure of module 10 and base 20 respectively.Referring to module section shown in Figure 1; this module section is the improvement of making on the traditional structure basis; traditional modular structure is to be provided with thermistor valve block 2 at the middle part of housing 1; the direct connection electrode 62 of one end of this valve block 2; connection electrode 61 after the other end is connected with thermal cut-off and overcurrent protector, what the thermal cut-off in the diagram adopted is low temperature weld tabs 3.Status display panel 4 one ends are that low temperature weld tabs 2 is connected with thermal cut-off, are connected by extension spring 5 between the other end and the shell 1.The utility model is further to be provided with temperature-sensitive device such as thermistor 7 on the said structure basis, this thermistor 7 is close on the thermistor valve block 2, and the performance index of thermistor 7 is delivered to the monitoring system of outside by contact pin 8.
During use, thermistor 7 adopts mounting method, be close on the thermistor valve block 2, and adopt Embedding Material fastening, real time temperature with maximum possible induction temperature-sensitive resistor valve sheet 2, the two poles of the earth of thermistor 7 are stretched out housing 1 by contact pin 8 and are connected with function terminal on the base 20, the state of output thermistor 7---also reflect the real time temperature of thermistor valve block 2, for the microcomputer detecting system collection analysis, when the performance of thermistor valve block 2 exceeds standard but be not badly damaged, carry out early warning, and the number of times of thermistor valve block 2 effective conducting surges is realized counting by various data analyses by microsystem.
And when the serious deterioration of performance index of thermistor 7; low temperature weld tabs 3 fusing as thermal cut-off; low temperature weld tabs 3 and being connected of thermistor valve block 2 are drawn back by status display panel 4 by extension spring 5; make surge protector break away from protected equipment; and display module 10 is badly damaged, can not use.
Fig. 2 has provided the structure of base 20, this base 20 also is the improvement to conventional base, on the conventional base basis, add the separated time function, have separated time copper component 11 in the base 20 and form a passage that is electrically connected, in two protruding ends of recess, design has the connector 12 that links to each other with module electrodes 61, and this connector 12 is connected with separated time copper component 11 in pedestal.In addition, the structure of these base 20 fit module 10 is provided with the access terminal 9 of contact pin in the bottom, and has designed lead-out terminal 10 at a side of base 20, and the connecting line that inserts between terminal 9 and the lead-out terminal 10 is arranged in the pedestal of base 20.
