Technical field
The present invention relates to a kind of three position interlocking devices of drawer type universal frame circuit breaker; Be applied to have the low pressure drawer-type omnipotent breaker of omnipotent breaker body and drawout chassis; Have breaker body in drawout chassis with the separating of major loop, test, be connected, the snap close of three positions and the interlocking of three positions, relate to the low voltage electrical apparatus technology field.
Background technology
Along with the technology maturation and the application of low-tension intelligent type omnipotent breaker, make the low-tension intelligent type omnipotent breaker realize development fast.Especially the intelligent universal frame circuit breaker is constantly accelerated to intellectuality, miniaturization, high breaking capacity direction developing progress.Market constantly increases the demand of intelligent universal frame circuit breaker, has also promoted the development of intelligent universal frame circuit breaker.
Series Circuit Breakers such as the alternative traditional DW10 of intelligent universal frame circuit breaker, DW15, ME form many-sided the breakthrough to the distribution network in electric power system and circuit, equipment protection function aspects.Have the intelligent protection function, have higher accurate selectivity, improved power supply reliability, avoid unnecessary power failure.Combination through many intelligent frame circuit breakers in power supply-distribution system can realize combined network communication, unified centralized monitor, the autonomous cooperation forming intelligent power supply-distribution system network.
Because the intelligent universal frame circuit breaker is in the intelligent power supply-distribution system network application of reality, existence can not provide the problem of position interlocking with the home state confirmation, can not satisfy the function needs of breaker body and drawout chassis major loop interlocking.The application technology that in known intelligent universal frame circuit breaker drawer type product, lacks the application site interlocking, therefore, the interlock of breaker body and drawout chassis major loop necessitates in user's practice.
In drawer type intelligent universal frame circuit breaker; The location status pressure that the relative position interlocking can satisfy intelligent universal framework withdrawable circuit breaker is set; Being to the replenishing of withdrawable circuit breaker application technology, is the improvement to drawer type intelligent universal frame circuit breaker technology.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can satisfy the compulsory device of location status of intelligent universal framework withdrawable circuit breaker, the technology of limiting circuit breaker body position state.Provide a kind of ability to satisfy the mechanism that breaker body and drawout chassis major loop is connected, tests, separates the interlocking of three positions.
The present invention realizes above-mentioned purpose through following technical scheme: a kind of position interlocking of universal framework withdrawable circuit breaker and the mechanism of position constraint, described universal framework withdrawable circuit breaker comprises universal frame circuit breaker body, drawout chassis.Interlock in described position and the mechanism of location status constraint is installed in the base plate of drawout chassis, sold and formed by position linking lever, pin, actuating lever, fixing support guide, keeper, reseting pressuring spring, reset tension spring, the extension that resets.Described fixedly support guide is riveted on the circuit breaker drawer-bottom board; Described position linking lever is installed in fixing the support on the guide; Described keeper is screwed on the drawout chassis base plate; Described actuating lever is installed between the base plate front and keeper of drawout chassis, and the reseting pressuring spring encapsulation is fixed on the actuating lever and with securing member, on keeper, prevents that with finger setting the actuating lever shaft from rotating; Described pin is riveted on the linking lever of position; The described extension pin that resets is riveted on the linking lever of position; Described reset tension spring is installed in fixing support guide and resets and hangs between the pin, with resetting of pulling linking lever.
" three positions " described in the present invention is meant: the correspondence position of withdrawable circuit breaker body and drawout chassis major loop is respectively: connect, test, separate.
One of characteristics of the disclosed technical scheme of the present invention are to be connected, to have when test, separation point position interlock relatively with the major loop of drawout chassis at breaker body.When needs change the relative position of breaker body and drawout chassis major loop, must carry out manual work and confirm and release.
Two of the characteristics of the disclosed technical scheme of the present invention are in the relative actuating mechanism separate mutually noninterfere that be connected, test, separate each position of breaker body with the drawout chassis major loop.
