Although the sensitive switch that above-mentioned these gas density relays adopt has advantages of good electric property, but because the length of contact motion arm 12 is longer, and be a cantilever beam, key is that its impact or oscillatory torque are large, in the time of operation sulphur hexafloride circuit breaker, cause contact motion arm 12 to vibrate very large, and then cause that misoperation appears in sulfur hexafluoride gas density relay, and even occur damaging sensitive switch, lose performance completely, resistance to shock is poor in a word, is difficult to ensure system reliably working.And the mode parallel with the Width of Baden's pipe 3 of sensitive switch 101,102,103 Widths with its operating grip in these gas density relays arranges, make the thickness of these density monitors thick, while particularly needing three～tetra-contacts, its thickness is very thick, is difficult to meet various application places.
In patent 200610023139.3, 200610118940.6(see Fig. 3 and Fig. 4) in disclosed gas density relay, the sensitive switch adopting has advantages of good electric property, but because the length of contact motion arm 16 is longer, and be a cantilever beam, key is that its impact or oscillatory torque are large, in the time of operation sulphur hexafloride circuit breaker, cause contact motion arm 16 to vibrate very large, and then cause that misoperation appears in sulfur hexafluoride gas density relay, that is to say that its resistance to shock is bad, can not ensure system reliably working, bring great hidden danger to the safe operation of electrical network.These sulfur hexafluoride gas density relays can not meet the reclosing requirement of sulphur hexafloride circuit breaker simultaneously.Be the blowing pressure (density) below alarm pressure value time, the shock test that can not bear 50g, 11ms, can there is misoperation in locking contact now.For example: the density monitor of 0.6/0.52/0.5, in the time that gas pressure (density) drops to actuation of an alarm point, now carry out the shock test of 50g, 11ms, can there is misoperation in locking contact, switch is carried out to locking, can not meet the reclosing requirement of sulphur hexafloride circuit breaker.Its resistance to shock is also undesirable in a word, is difficult to ensure system reliably working.Equally, sensitive switch 91,92,93 Widths with its operating grip in these gas density relays mode parallel with the Width of Baden's pipe 6 arranges, make the thickness of these density monitors thick, while particularly needing 3～4 contacts, its thickness is very thick, is difficult to meet various application places.
See Fig. 5 and Fig. 6 in patent 201020190271.5 and 201010171798.8() disclosed gas density relay also comprises displacement amplifying mechanism, the initiating terminal of this displacement amplifying mechanism is connected with the other end of temperature-compensating sheet, hold and amplify the contact operating grip that drives sensitive switch, the contact on sensitive switch is switched on or switched off; When gas density value changes, Baden's pipe and temperature-compensating sheet produce displacement, and this displacement passes to sensitive switch after amplifying by displacement amplifying mechanism, makes sensitive switch send corresponding signal, completes the function of density monitor.But, when sulphur hexafloride circuit breaker carries out breaking-closing operating, can produce vibration to Baden's pipe and temperature-compensating sheet, this vibration can cause that Baden's pipe and temperature-compensating sheet are subjected to displacement, this displacement passes to sensitive switch after also amplifying by displacement amplifying mechanism, makes sensitive switch send corresponding signal.Will produce like this misoperation, that is to say that its resistance to shock is bad, can not ensure system reliably working, bring great hidden danger to the safe operation of electrical network.These sulfur hexafluoride gas density relays can not meet the reclosing requirement of sulphur hexafloride circuit breaker simultaneously.Be the blowing pressure (density) below alarm pressure value time, the shock test that can not bear 50g, 11ms, can there is misoperation in locking contact now.For example: the density monitor of 0.6/0.52/0.5, in the time that gas pressure (density) drops to actuation of an alarm point, now carry out the shock test of 50g, 11ms, can there is misoperation in locking contact, switch is carried out to locking, can not meet the reclosing requirement of sulphur hexafloride circuit breaker.And the problem of patent 200520115321.2 is similar to patent 201010171798.8, also be vibration can be caused displacement pass to sensitive switch after amplifying by displacement amplifying mechanism and (pass to controller mandrel by controlling sector gear, pass to sensitive switch through controller mandrel again), amplify so widely the displacement that vibration causes, be equivalent to make vibration to become more severe.Due to very large in the time vibration of sulphur hexafloride circuit breaker breaking-closing operating, need especially the better gas density relay of resistance to shock, above-mentioned these gas density relays can not be dealt with.Equally, sensitive switch 101,102,103 Widths with its operating grip of these gas density relays mode parallel with the Width of Baden's pipe 6 arranges, make the thickness of these density monitors thick, while particularly needing 3～4 contacts, its thickness is very thick, is difficult to meet various application places.
In addition, patent 200810201462.4(is shown in Fig. 7) disclosed a kind of gas density relay, although contact has also adopted sensitive switch, also be provided with the regulating part corresponding with sensitive switch 141～143 and contact operating axis 16, wherein, one end of contact operating axis 16 is connected in the rotating shaft 24 of sector gear of movement 2 and rotates with the rotating shaft 24 of this sector gear, on this contact operating axis 16, compartment of terrain radially offers the threaded perforations corresponding with sensitive switch 91～93 along its length, regulating part 141～143 is plugged in threaded perforations correspondingly and its end is resisted against on the operating grip of sensitive switch 91～93.Rotate by the contact operating axis 16 being fixed in the rotating shaft 24 of sector gear, the regulating part 141～143 that makes to be fixed on this contact operating axis 16 drives sensitive switches 91～93 actions.Because the rotational angle of the rotating shaft 24 of sector gear is very little, the precision of product is reduced.More seriously because the actuating length of the operating grip of sensitive switch is short, be adjustment screw and regulating part 141～143 adopts.In the time that Baden's pipe 6 moves, sector shaft 24 with movement 2 rotates, make adjustment screw rotate the operating grip of encountering sensitive switch, and then the moving contact of driving operating grip push switch, when turning in the situation that the end face of adjustment screw and the operating grip of sensitive switch are vertical, adjustment screw is blocked and can not have been rotated, so be difficult to the density monitor of the gamut of realizing-0.1～0.9MPa, particularly be difficult to realize the demonstration of be initiated with-0.1MPa, while vacuumizing, just cannot show, be difficult to apply.Equally, the sensitive switch 91～93 of this gas density relay arranges in the Width of its operating grip mode parallel with the Width of Baden's pipe 6, makes the thickness of this density monitor thick, while particularly needing 3～4 contacts, its thickness is very thick, is difficult to meet various application places.So be starved of innovation.
Patent 200810201462.4(is shown in Fig. 8 in addition) disclosed a kind of gas density relay, although contact has also adopted sensitive switch, also increase anti-error operation mechanism, improve resistance to shock.Equally, the sensitive switch 91～93 of this gas density relay arranges in the Width of its operating grip mode parallel with the Width of Baden's pipe 6, add and increased anti-error operation mechanism, make the thickness of this density monitor thick, while particularly needing 3～4 contacts, its thickness is very thick, is difficult to meet various application places.So be starved of innovation.
