Abstract
The utility model relates to a separate excited releaser assembly used with breaker. The device mainly comprises a shell base, a handle, a trip mechanism and a contact device. The utility model is characterized in that the pressure loop of the trip mechanism is connected in series with the constant closed contact of the thermistance and relay; a loop is formed and is connected with the main circuit, and the loop is controlled by the relay and the pressure lower commute circuit. The electricity input terminal is designed as a control terminal and is connected with the phase conductors. The problem of time delay of the trip mechanism is solved. The device can let the assembled breaker proceed a remote disjunction or automatic signal controlled disjunction, which is more suitable to the occasion that the disjunction is not allowed for the instant of electricity breaks off.
Description
The utility model relates to the low-voltage electrical apparatus switch, the equipped switching device that uses of specifically a kind of and circuit breaker.
General shunt release is made up of protection contact, potential winding, armature, yoke and antagonistic spring.Existing sheet composite type shunt release with the circuit breaker adapted is the version of instantaneous operation.This shunt release is then mainly by outer shell base, termination, handle, tripping mechanism, operating mechanism, and contact apparatus is formed, its tripping mechanism then includes potential winding, moving iron core, fixed core and push rod, after the potential winding energized, drive the actuating mechanism action by its armature, make circuit breaker tripping and tripping realization disjunction.
The purpose of this utility model is that a kind of band delay function shunt release will be provided.It is the flat sheet-like structure, can carry out simple and easy quick installation so that compound mode and circuit breaker are supporting.
The purpose of this utility model is achieved in that this shunt release, mainly by shell block, termination, handle, tripping mechanism, operating mechanism, contact apparatus is formed, its tripping mechanism includes potential winding, moving unshakable in one's determination, fixed core and push rod is characterized in that: said potential winding and a thermistor, the normally closed interlock of a pair of relay is in series, and receives the two ends of main circuit power, the output of this a relay actuating coil and a step-down rectifying circuit joins, the input of rectification circuit, the earth terminal of a termination power, the other end is connected with the phase line of external power supply.
Good effect of the present utility model is as follows:
Owing to be provided with thermistor in the tripping mechanism, when control circuit cuts off the power supply, make the coil control circuit dead electricity of relay, its normally closed interlock returns to the closure state when originally not switching on, the thermistor energising, resistance descends gradually, electric current increases, and produces time-delay, up to the electromagnetic force promotion armature movement of driving voltage coil, finish dropout, thereby realized the time-delay disjunction of circuit breaker.
Secondly, its structure is small and exquisite, can be satisfied with the needs of laminated structure, is suitable for installing and using among the block terminal of composite type assembling.
Describe below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be tripping mechanism structural representation.
Fig. 3 is the electrical connection diagram of embodiment.
Fig. 4 is in running order example structure schematic diagram.
Referring to accompanying drawing.Among the embodiment shown in Figure 1, the outward appearance of shunt release is identical with sheet packet type switch spare, and this structure is convenient to equipped, the replacing of integral type.In shell block 1, be provided with termination 2, handle 4, operating mechanism 5, tripping mechanism 3, and contact apparatus and associated moving part.Compact conformation, complete.The 6th, the thermistor of time-delay usefulness.The 7th, conducting rod is done switching and is connected usefulness, and nationality inserts power end on one side with the circuit breaker that connects from the side.The 8th, control circuit device.The 9th, the circumscription socket of external control end usefulness.
Tripping mechanism wherein as shown in Figure 2, it mainly is made up of potential winding 11, moving unshakable in one's determination 10, fixed core 12, push rod 13, wherein potential winding 11 is connected with thermistor 6.By coil current with the adhesive of the variation of resistance and magnetic bobbin core and the release action control of threading off.
Shown in Figure 3 is the electric hookup of embodiment.L is the electric network source phase line, and N is a ground wire.Its switch contact is two pairs of contacts in the contact apparatus, and the moving contact 15 among Fig. 4, fixed contact 16 are wherein a pair of, and another is to being located at the same position shown in the drawing, and is down below topped.From one of them moving contact-thermistor-potential winding L
1The fixed contact of another moving contact correspondence of-relay constitutes one by normally closed interlock J
1-1The work loop of control.This end is electrically connected with conducting rod.Rectification circuit and a decompression capacitor C are connected to form step-down rectifying circuit.Its output connects the coil L of relay J
2, for it provides operating current.The input of step-down rectifying circuit, on the earth connection N of one termination power, the movable contact head end of promptly corresponding its earth connection, the other end picks out power input into step-down rectifying circuit from reducing capacitor C, and holding concurrently is control end, and is connected with phase line.K represents main circuit (electric current) contact.
Figure 4 shows that the configuration state figure when being in operate as normal.Wherein handle 4 has been pushed to right-handly, and operating mechanism 5 has moved, and 14 is back-moving spring, is compressed.Moving contact 15 also engages with fixed contact 16.Other turnover line, control end connection are set all ready, then have been in normal operating conditions this moment.
Below sketch dynamic duty process of the present utility model:
1. during operate as normal, external control end is phase-connecting wire, and the step-down rectifying circuit conducting is started working, and relay coil has energising work, and normally closed interlock is opened, and potential winding and thermistor and main circuit are disconnected;
2. when external control end opens circuit for some reason, the output of rectification circuit non-transformer, the relay outage, its normally closed interlock closure, potential winding and thermistor insert main circuit, work loop conducting, thermistor energising back resistance diminishes gradually, circuital current increases gradually, when the electromagnetic force that potential winding is produced is enough to promote the moving unshakable in one's determination and push rod that links with it, drive the action of operating mechanism and handle, make contact separately, under the drive of link gear, make simultaneously equipped circuit breaker realize disjunction, reach the purpose of time-delay shunted exciter tripping.
3. after the accident for the treatment of is got rid of, at first control end is connected, made relay power, disconnect its normally closed interlock, handle is pushed in the potential winding outage again, and working contact is kept in touch, and this shunt opening release enters normal operating conditions again.
This device and circuit breaker be close to mutually equipped after, during the circuit breaker conducting, it is electric by conducting rod above-mentioned work loop to be got, and sets up operating state.Conversely, when one disconnection of external circuit breaker, conducting rod and main circuit reliably break away from, and this release apparatus also just is separated from power supply.
Adopt this device can make equipped circuit breaker carry out remote disjunction control or automatic signal control disjunction, because of it has delay function, so be specially adapted to require not allow the place of disjunction in the moment of cutting off the power supply.Can prevent instantaneous tripping operation.
