Abstract
The utility model relates to a shunt tripping device, in particular to a shunt tripping device with a casing in which a group of auxiliary contacts are arranged, and a power supply of the auxiliary contacts is different from a power supply of a shunt tripping coil of the shunt tripping device. The shunt tripping device adopts the technical scheme as follows: the shunt tripping device with the auxiliary contacts comprises a casing, a shunt tripping unit and an auxiliary contact unit, wherein the shunt tripping unit and the auxiliary contact unit are arranged in the casing; and the shunt tripping unit comprises a handle, a tripping mechanism and a contact mechanism. The hunt tripping device is characterized in that the power source of the auxiliary contact unit is separated from that of a coil of the shunt tripping unit. With the adoption of the technical scheme, the utility model solves the defects in the prior art and provides the novel shunt tripping device with a casing in which the auxiliary contacts are arranged, further the power source of the auxiliary contacts is different from that of the coil of the shunt tripping unit.
Description
Technical field
The utility model relates to a kind of shunt release, is meant especially in the housing of shunt release, to be provided with one group of auxiliary contact, and the power supply of the auxiliary contact shunt release different with the power supply of the shunt opening trip coil of shunt release.
Background technology
Shunt release on the existing market has two kinds, a kind of is the shunt release of function singleness, its inside only has only the shunted exciter tripping unit, another kind also is provided with one group of auxiliary contact unit except the shunted exciter tripping unit is set in the plastic casing of 18mm, but the shared end points of the coil of this auxiliary contact unit and shunted exciter tripping unit, therefore, this auxiliary contact unit must use same power supply with the coil of shunted exciter tripping unit, otherwise the shunted exciter tripping unit can't operate as normal.When if the coil of customer requirement auxiliary contact unit and shunted exciter tripping unit uses different electrical power, must be on shunt release next door independent auxiliary contact of assembly unit again, so both increase cost, taken the space of user's distribution board again, also increased the difficulty of user's assembly unit.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, and provide a kind of and in the housing of shunt release, be provided with one group of auxiliary contact, and the different novel shunt release of power supply of the power supply of auxiliary contact and the coil use of shunted exciter tripping unit.
Realize above-mentioned purpose, the utility model adopts following technical scheme, a kind of shunt release with auxiliary contact, include housing, be arranged on shunted exciter tripping unit and auxiliary contact unit in the housing, the shunted exciter tripping unit includes handle, tripping mechanism and contact mechanism, it is characterized in that: the power supply of described auxiliary contact unit is independent of the power supply of the coil use of shunted exciter tripping unit.
By adopting such scheme, we are provided with one group of auxiliary contact unit in housing, and the power supply that this auxiliary contact unit uses is different with the power supply that the coil of shunted exciter tripping unit uses, can under different voltage, use this shunt release like this, bring a lot of convenience for user's use, type selecting.
Further setting of the present utility model is: described auxiliary contact unit includes moving contact, two groups of fixed contacts, pull bar and pivoted arms, described two groups of fixed contact fixed card are connected in the housing, described two groups of fixed contacts are for disconnecting fixed contact and conducting fixed contact, described pivoted arm one end is fixedly installed on the contact of shunted exciter tripping unit and supports, the other end is connected with moving contact by connector, moving contact switches mutually with the rotation and two fixed contacts of pivoted arm, described housing is provided with fixture block, and the fixed contact of auxiliary contact unit is fastened on the housing by fixture block.
By adopting such scheme, more reasonable when the control moving contact turns to disconnection fixed contact and conducting fixed contact, make moving contact constitute auxiliary contact and become often to open or normally off with the cooperation of two fixed contacts.
Of the present utility model further the setting again is: an end of described pull bar is set with boss, the hinged moving block that is provided with on the other end, described moving block rotates and is arranged on the housing, be provided with back-moving spring between moving block and the housing, moving block its other end with respect to hinged end under the drive of pull bar becomes to compress cooperation with the yoke of shunted exciter tripping unit, and lug boss position relative and pull bar is provided with through hole on the described housing.
Adopt such scheme, can be when shunt release and circuit breaker be used, connecting rod penetrates through hole and cooperates with the boss of pull bar, like this circuit breaker when disconnection, connecting rod drive pull bar, pull bar spurs moving block, and auxiliary contact is also disconnected.
Below in conjunction with accompanying drawing the utility model embodiment is further described.

Embodiment
As Fig. 1---shown in Figure 7, a kind of shunt release with auxiliary contact, include housing 1, be arranged on shunted exciter tripping unit 2 and auxiliary contact unit 3 in the housing 1, shunted exciter tripping unit 2 includes handle 21, tripping mechanism and contact mechanism, in the utility model embodiment, the power supply of described auxiliary contact unit 3 is independent of the power supply of the coil use of shunted exciter tripping unit 2.Adopt such scheme, we are provided with one group of auxiliary contact unit 3 in housing 1, and the power supply that this auxiliary contact unit 3 uses is different with the power supply that the coil of shunted exciter tripping unit 2 uses, can under different voltage, use this shunt release like this, bring a lot of convenience for user's use, type selecting.
In the utility model embodiment, described auxiliary contact unit 3 includes moving contact 31, two groups of fixed contacts 32, pull bar 33 and pivoted arm 34, described moving contact 31 is hinged on the housing 1, described two groups of fixed contact 32 fixed card are connected in the housing 1, described two groups of fixed contacts 32 are for disconnecting fixed contact and conducting fixed contact, one end of described pull bar 33 is set with boss 331, the hinged moving block 332 that is provided with on the other end, described moving block 332 rotates and is arranged on the housing 1, be provided with back-moving spring 334 between moving block 332 and the housing 1, moving block 332 its other end 3321 with respect to hinged end under the drive of pull bar 33 compresses cooperation for 22 one-tenth with the yoke of shunted exciter tripping unit, boss 331 positions relative and pull bar 33 are provided with through hole on the described housing 1, like this when shunt release and circuit breaker are used, connecting rod can penetrate through hole and cooperate with the boss 331 of pull bar 33, when circuit breaker disconnects, connecting rod drives pull bar 33, pull bar 33 pulling moving blocks 332 finally make auxiliary contact also disconnect; One end of described pivoted arm 34 is fixedly installed on the contact of shunted exciter tripping unit 2 and supports on 23, the other end is connected with moving contact 31 by connector 341, pull handle 21 like this, thereby pivoted arm 34 also rotated simultaneously and drives moving contact 31 and switches between two fixed contacts 31 when contact supported 23 to rotate, and main purpose is auxiliary contact unit and disconnection of shunted exciter tripping units synchronization or combined floodgate.More reasonable when control moving contact 31 turns to disconnection fixed contact and conducting fixed contact in the such scheme, make moving contact 31 constitute auxiliary contact and become often to open or normally off with the cooperation of two fixed contacts 32.In the utility model embodiment, described housing 1 is provided with fixture block 11, and the fixed contact 32 of auxiliary contact unit is fastened on the housing 1 by fixture block 11.
