Abstract
The invention provides a micro electronic controlled releaser for electrical apparatus components, making low-voltage electrical apparatus components (such as low-voltage breaker, etc.) that have short-circuit analyzing ability and inverse time limit overload protecting ability, able to implement long-distance and automatic control of closing, breaking or free releasing of their main contactors without any external auxiliary equipment. And it comprises a main body and its characters lie in that: it is provided with auxiliary normally closed contact, which is connected in series with electronic control line and breaks the power supply of an actuating component by breaking the electronic control line to control the on or off of the main contactor. The electronic control line can be added with multiple protecting circuits, such as the protecting circuits for leakage, undervoltage, phase failure, phase sequence, etc. Multiple uses and functions can share a releaser and is not limited by the position; the occupied space is reduced, the investment cost is reduced and the reliability is improved, thus implementing long-distance and automatic control of closing, breaking or free releasing of the main contactor. By probation, the effect is extremely excellent.
Description
1, technical field
The invention belongs to the release technical field of low voltage component.Definite says, it is the release with the low voltage component of microelectronics control.
2, background technology
The release of traditional electric elements with short circuit and inverse time lag overload protection function; be mechanical type; its shortcoming is can not be remote; concentrate; automatically; (control is closed in the operation of upper frequency; separating brake); the design of some occasions must be at a distance; when circuit breaker concentrated or operation control automatically or similar low-voltage electrical apparatus; having to be equipped with the motor-operating mechanism that price is higher than electrical equipment own realizes at a distance; centralized operation control; and because of supporting assembling process; non-same plant design manufacturing is finished, so its quality of fit; reliability; life-span and frequency of operation all can have problems.
3, summary of the invention
The invention provides a kind of release device of the electric elements with microelectronics control; make low voltage component (as: low-voltage circuit breaker etc.) with short circuit breaking capacity and inverse time lag overload protection function; do not needing to add under the situation of auxiliary equipment; can realize controlling at a distance, automatically its main contact closure, disconnection or trip free.
Its purpose is realized by following technical proposals; it comprises the release body of each self-protection function; its characteristics are: it is provided with auxiliary normally closed interlock; auxiliary normally closed interlock is connected on the electronic control circuit; link to each other control main contact break-make by the control actuating component of circuit with the low voltage component main contact.
The release body has various ways, as: the release of the screw magnetictrip of short-circuit protector (interior is shuttle armature type), overload protective device (interior is thermal element deformation displacement formula) etc.Because being the mechanical energy will be threaded off by release separately the time, these dropouts convert the signal of telecommunication to by auxiliary contact; Because the operating system that is switched on or switched off of the main contact of the low voltage component that these releases are supporting with it is that electric operating mechanism is (as custom-designed relay; apply for a patent in addition); so its disconnection is the power supply that is disconnected electric operating system by the auxiliary normally closed interlock of each self-protection function release; make electric operating mechanism disconnect the main contact of electric elements, realize protection.In like manner, can realize the power supply of the electric operating system of remote electricity consumption signal controlling electric elements (as: relay), realize the disjunction of connection formula by lead.
Electronic control circuit can increase the kinds of protect functional circuit as required, as: electric leakage, under voltage, phase shortage, phase sequence or the like defencive function circuit.But the shared release of multiple use function, and be not subjected to the restriction of position; Dwindle taking up room, reducing cost input, raising reliability, thereby realize manually or automatically controlling its main contact closure at a distance, disconnect or trip free.
4, description of drawings
Fig. 1 is one of embodiments of the invention (when overload and two kinds of situations of short-circuit protection).
5, embodiment
As shown in Figure 1: " short-circuit protector "; be short-circuited moment of fault at a controlled circuit (main circuit); the iron core of the screw rod magnetictrip of " short-circuit protector " moves rapidly; push the auxiliary normally closed interlock that is connected on the electronic control circuit open; the relay main contact is controlled by auxiliary normally closed interlock; therefore; can disconnect the working power of " relay "; make " relay " main contact because of can not get closed electromagnetic attraction; and under the effect of reaction spring and disconnect; thereby the open failure electric current reaches the purpose of protection.
" overload protective device " is at a controlled circuit (power consumption equipment); being in operation, (being included in emerged in operation lacks when producing above design load; the phase failure and make other biphase current become big); the thermal element of " overload protective device " will produce displacement regularly; promotion is connected on the auxiliary normally closed interlock on the electronic control circuit; the relay main contact is controlled by auxiliary normally closed interlock; therefore; can disconnect the working power of " relay "; make " relay " main contact because of can not get closed electromagnetic attraction; under the effect of reaction spring and disconnect; thereby the open failure electric current, the purpose of realization overload protection.
The present invention is through on probation, and effect is splendid.
Claims (2)
1, with the release of the electric elements of microelectronics control, it comprises the release body, it is characterized in that: it is provided with auxiliary normally closed interlock, auxiliary normally closed interlock is connected on the electronic control circuit, by disconnecting electronic control circuit, disconnect the power supply of executive component, control main contact break-make.
2, according to the release of the described electric elements with microelectronics control of claim 1, electronic control circuit can increase the kinds of protect functional circuit as required, as: electric leakage, under voltage, phase shortage, phase sequence or the like defencive function circuit.
