Abstract
The utility model discloses a tap measuring terminal of high voltage electrical apparatus which includes a tap lead, an earthing device and a measuring part; the tap measuring terminal of high voltage electrical apparatus is characterized in that the measuring part is a sleeved type measuring sensor which is sleeved at the outside of the tap lead and is arranged inside the earthing device; and the tap lead is fixedly connected with the earthing device through a nut. The tap measuring terminal of high voltage electrical apparatus uses the sleeved type measuring sensor to directly arrange the measuring part into the tap measuring terminal; therefore, the tap measuring terminal of high voltage electrical apparatus can directly obtain a needed signal and is connected with a digital processing system to realize online monitoring on high-voltage electrical apparatus without needing to open the earthing of the tap measuring terminal.
Description
Technical field
The utility model relates to a kind of end screen terminal of High-Voltage Electrical Appliances, belongs to the electrical equipment technical field.
Background technology
For High-Voltage Electrical Appliances contingent fault in service is detected, the on-line monitoring mode of widespread usage is at present: extract signal from end screen (voltage tap) terminal of high-voltage capacitance formula product (as bushing), offer corresponding Data Management Analysis system and analyze, provide the ruuning situation of current high voltage electric appliance.Necessary ground connection when the end screen terminal of High-Voltage Electrical Appliances moves, but above-mentioned when High-Voltage Electrical Appliances end screen terminal extracts signal, exist the process should end screen terminal ground connection opened of needing, again this ground connection is drawn ground connection (or transform the screen terminal of the end on the original product) separately.These work, the reliability that greatly reduces original product end screen terminal ground connection so undoubtedly; Therefore, once repeatedly took place to cause bottom shielding of bushing terminal open circuit, thereby made the accident of casing damage because repacking is bad.For this reason electrical network company special civilian requirement is arranged, do not allow to carry out such and transform the visiting on-Line Monitor Device of installing.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, do not influence the ground connection reliability, can be directly provide the end screen terminal of line monitor signal for operating High-Voltage Electrical Appliances.
For solving the problems of the technologies described above, the utility model provides a kind of High-Voltage Electrical Appliances end screen measurement terminal, comprise end screen lead-in wire, earthing device and measurement component, it is characterized in that: described measurement component is the sleeve type survey sensor, described sleeve type survey sensor is enclosed within the screen lead-in wire outside, end, and being positioned at earthing device, end screen lead-in wire is fixedlyed connected with earthing device by nut.
Aforesaid High-Voltage Electrical Appliances end screen measurement terminal is characterized in that: be provided with packoff in described sleeve type survey sensor upper end with the earthing device joint.
The beneficial effect that the utility model reached:
High-Voltage Electrical Appliances of the present utility model end screen measurement terminal, by adopting the sleeve type survey sensor, to measure (sensor) parts directly is arranged in the screen measurement terminal device of end, so need not open the ground connection of end screen measurement terminal, just can directly obtain desired signal, offer the corresponding digital disposal system, realize on-line monitoring High-Voltage Electrical Appliances.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of existing High-Voltage Electrical Appliances end screen terminal.Existing end screen terminal comprises measurement component 12 and earthing device 11, in the time of need installing on-line monitoring as the user, earthing device on the high voltage electric appliance is discarded invalid, and need its ground connection (comprising end screen terminal lead) is drawn out to other places separately, ground connection again after required survey sensor connected, thus the reliability of high voltage electric appliance ground connection influenced easily.
Fig. 2 is the structural representation of High-Voltage Electrical Appliances of the present utility model end screen measurement terminal.
A kind of High-Voltage Electrical Appliances of the present utility model end screen measurement terminal, comprise end screen lead-in wire 1, earthing device 4 and measurement component, it is characterized in that: described measurement component is a sleeve type survey sensor 5, described sleeve type survey sensor 5 is enclosed within screen lead-in wire 1 outside, end, and being positioned at earthing device 4, end screen lead-in wire 1 is fixedlyed connected with earthing device 4 by nut 2.Be provided with packoff 3 in described sleeve type survey sensor 5 upper ends and earthing device 4 joints.
The end screen terminal structure of High-Voltage Electrical Appliances of the present utility model, original end screen measurement terminal is improved, and employing sleeve type sensor construction, whole detection sensor unit all is contained in the screen terminal of end, the user does not need to change former bottom shielding of bushing structure and the end screen is in when moving ground state all the time, can provide the operating state signal of high voltage electric appliance incessantly, to offer on-line monitoring.
Claims (2)
