Description
Technical field
The utility model relates to a kind of charged connection device, the charged access device of particularly a kind of portable standard capacitance.
Background technology
In electric system; Often need at the scene equipment to be carried out high-potting and insulating monitoring, and existing busbar voltage acquisition methods all is directly to read its secondary voltage through the voltage sensor secondary side; Because the characteristics of device own determine; Secondary voltage phase place and actual value have certain deviation, and the size of this deviation can directly cause the inaccurate of insulated on-line monitoring data, and the insulation situation of converting equipment is caused erroneous judgement.The frequency that this erroneous judgement occurs is very high; Cause on-the-spot on-line equipment confidence level to reduce; Its original purpose and practicality be forfeiture gradually also; Press for for this reason and a kind ofly can be at any time secondary voltage phase place and amplitude be realized the device proofreaied and correct, so that voltage-phase and amplitude parameter accurately to be provided, the test data of gained just can be used in the accurate judgement of apparatus insulated situation like this.Voltage-phase and amplitude parameter normally adopt the mode of standard capacitor dividing potential drop to obtain busbar voltage accurately in above-mentioned test, thereby obtain reference data, and this is a kind of very effective mode.Yet, but be under the state that has a power failure, to insert bus as the bleeder mechanism of standard capacitor, otherwise safe reliability can't guarantee that the while also can be caused bigger disturbance to network system; On the other hand, because the access calibration equipment that will often have a power failure in the test process also causes test effect not good, the quality of data is low, and also very inconvenience when changing access point.
The utility model content
The purpose of the utility model is that the weak point according to prior art provides a kind of safe, little to grid disturbance, plug and play, inserts and the charged access device of portable standard capacitance at any time.
The purpose of the utility model realizes through following approach:
The charged access device of portable standard capacitance includes standard capacitor, and its structural feature is; Include motor, transmission platform, gearing, crane and bus access device, standard capacitor is installed in the transmission platform below, and crane is installed in the transmission platform top; Be in transmission connection with gearing; The bus access device is installed on the platform on crane top, and motor is connected with gearing, and crane is connected to standard capacitor through electric installation; Its median generatrix access device and crane are conductive material and process, and gearing adopts insulating material to process.
When inserting the bus operation, actuating motor, gearing is started working; And the drive crane raises; The bus access device moves closer to the bus access point along with the rising of crane, the control motor speed makes the bus access device be connected on the bus, because bus access device and crane are electric installation; Therefore just realized also that standard capacitor is electrically connected with bus through electric installation, crane, bus access device in regular turn, accomplished the charged access of standard capacitor.Because mostly whole process is mechanical drive, simple operation is safe; Insert and adopt the Motor Control crane to cooperate special-purpose bus access device, little to the disturbance of electrical network; Insulation by gearing realization raised portion and control section is isolated, and is easy, reliable, practical; Can plug and play, insert at any time because crane, gearing, standard capacitor etc. all are installed on the identical platform, globality is strong, is easy to dismounting and moves.
The utility model can further be specially:
The roller that gearing includes change gear group, nut screw component and is connected with crane; The change gear group connects motor and nut screw component respectively, and the nut screw component includes nut and screw mandrel, and nut wherein connects roller through connecting link; Roller is arranged in the guide rail that is provided with on the transmission platform; Crane is a kind of expansion bracket, and its bottom movable end is installed on the roller, and the bottom stiff end is installed on the bearing of another side of guide rail.
The change gear group is meant by 2 above gears to be formed, and can realize the gear set that transmission direction changes.Behind the actuating motor, the operation of motor drives change gear group drives screw mandrel by the change gear group and rotates, thereby makes nut parallel moving on screw mandrel, and on guide rail, moves guide rail and the screw mandrel plane distribution of this moment via connecting link drive roller.Along with the operation of nut screw component, the roller that has the expansion bracket movable end is along the translation of the guide rail left and right sides, thereby the motion that the drive expansion bracket stretches and shortens realizes the operation that raises and reduce.
Because above-mentioned gearing will drive crane and realize the charged access bus of standard capacitor, so its structural requirement is easy, reliable, practical, and is detachable, can coordinate control to height simultaneously.The said gearing that is made up of change gear group and nut screw component has satisfied above-mentioned requirements, reaches whole control and coordinates, can have enough rising height, and enough reliabilities and enough light comprehensive purpose are arranged again.
The change gear group is that two bevel gears are installed composition with vertical distribution.
The bus access device includes conductive seat and is connected a plurality of arc surface electric contacts on the conductive seat.
Conductive seat is used for the bus access device is installed in the platform on crane top, and arc surface electric contact is arcs of recesses down, is used for connection bus, can the bus ring be trapped among in the concave arc, realizes connecting reliably.
Arc surface electric contact is generally two or more, and it specifically can be:
One of them arc surface electric contact is connected on the conductive seat through a damping resistance via power spring, and vertical height is higher than other arc surface electric contacts.
Because the bus access device is the connection that is used for high voltage bus, occur in order to prevent unstable situation such as arc light overvoltage, can insert the highest middle arc surface electric contact earlier; Its objective is for extinguishing arc electric current is passed through damping resistance earlier, and then insert all the other two arc surface electric contacts, guarantee reliably and accurately inserting of electric current; The concrete realization as follows: in the crane uphill process, because the arc surface electric contact of band power spring is higher than other contacts, so it must contact bus in advance; Accomplish connection, along with the further rising of crane, the power spring compression; The bus access device further rises; Other arc surface electric contact is also inserted bus, thereby accomplish safe and reliable charged access, avoided signal circuit and network system are caused disturbance.For further safety connection, the arc surface electric contact that has power spring is the epirelief curvic structure, when connecting, for a kind of point-like touches, avoids the generation of high-voltage arc like this.
In sum, the utility model provides a kind of portable standard capacitance charged access device, and it adopts crane to drive the bus access device and moves up; And charged access bus; Completion is charged, the safe and effective access bus of standard capacitor, the single unit system simple structure, volume is little, be convenient to take in and carry, simple operation, safe, little to grid disturbance; Can insert at any time, can move at any time according to the bus access point.
