Abstract
The utility model provides a high voltage handcart breaker contact finger detector characterized by comprising a housing and a handle connected with the housing; an end portion of the housing is provided with a groove; the housing can be conveniently plugged in the breaker contact finger so as to strut the contact finger, so the contact finger, a conductive rod, the housing and a breaker contact can form a loop; a lead-out line of the detector is connected with the handle so as to detect contact conditions of the loop formed by the contact finger, the conductive rod and the breaker contact. The high voltage handcart breaker contact finger detector is convenient and useful, simple in operation, accurate in detection, thereby reducing errors, and ensuring normal work of the breaker.
Description
Technical field
The utility model relates to a kind of pick-up unit, and particularly a kind of high-voltage handcart formula isolating switch touches pawl pick-up unit, belongs to electric equipment detector design and manufacturing technology field.
Background technology
Because high-voltage handcart formula isolating switch is installed in sealed cabinet, therefore it in use easily causes heating because touching pawl loose contact, even causes fault.In order to ensure that isolating switch can normally work, need regularly detect the contact situation of its tactile pawl.Prior art is that the extension line of measuring appliance is connected on isolating switch conducting rod and carries out contact detection, and which can only detect the conduction situation of conducting rod, cannot detect with the situation that contacts of tactile pawl conducting rod.In addition, need cut-off breaker when detection, the spring touching on pawl can make tactile pawl close up and depart from conducting rod, causes testing to complete.Therefore can only rely on artificial visual inspection to touch the situation that contacts of pawl and conducting rod, easily produce error, can not effectively find the hidden danger such as tactile latch spring fatigue and fingertip ablation, thereby affect the safe and stable operation of isolating switch.Therefore be necessary prior art to be improved.
Summary of the invention
The purpose of this utility model is to provide a kind of can carry out to the tactile pawl contact situation of high-voltage handcart formula isolating switch the device accurately detecting easily.
The utility model completes by following technical proposal: a kind of high-voltage handcart formula isolating switch touches pawl pick-up unit, it is characterized in that it comprises that its end establishes reeded valve jacket, and the handle being connected with valve jacket, so that valve jacket is inserted to isolating switch to be touched pawl inside and struts tactile pawl, thereby make to touch pawl, conducting rod, contact of breaker formation loop, again the extension line of detecting instrument is connected with handle, can detects the contact situation in this loop.
Described valve jacket is made as right cylinder, valve jacket top is made as cone, in cone, establish groove, valve jacket end is connected with handle, touch pawl inside, strut tactile pawl simultaneously to valve jacket is relatively easily inserted by cylindrical structure and pyramid tip, make to touch pawl and contact well with isolating switch conducting rod, the groove arranging in cone can effectively reduce valve jacket material usage, reduces costs.
Described handle comprises U-shaped metal frame, and be located at the level insulation rod at U-shaped metal frame top, the bottom of U-shaped metal frame is fixed by screws in valve jacket end, to detecting device extension line is connected on U-shaped metal frame, and conveniently holds level insulation rod and operates.
Described valve jacket is metal copper sheathing.
Described U-shaped metal frame is copper frame.
The utlity model has following advantages and effect: adopt such scheme, can easily valve jacket be inserted to isolating switch touches pawl inside and struts tactile pawl, make to touch pawl, conducting rod, valve jacket, contact of breaker formation loop, again the extension line of detecting instrument is connected with handle, can detects the contact situation in the loop of touching pawl, conducting rod, contact of breaker formation.Not only convenient and practical, simple to operate, and detect accurately, reduce error, ensure the normal work of isolating switch.Be a desirable handcart type breaker pick-up unit in fact.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, the high-voltage handcart formula isolating switch that the utility model provides touches pawl pick-up unit, comprises that its end is provided with the valve jacket 3 of groove 1, and the handle being connected with valve jacket 3; Described valve jacket 3 is made as right cylinder, and valve jacket 3 tops are made as cone 2, establish groove 1 in cone 2, and valve jacket 3 ends are connected with handle; Described handle comprises U-shaped metal frame 5, and be located at the level insulation rod 6 at U-shaped metal frame 5 tops, the bottom of U-shaped metal frame 5 is fixed on valve jacket 3 ends by screw 4, level insulation rod 6 two ends are connected with U-shaped metal frame 5 tops by screw bolt and nut 7 respectively, to detecting device extension line is connected on U-shaped metal frame 5, and conveniently holds level insulation rod 6 and operate.
When work: valve jacket 3 is inserted to isolating switch and touch pawl inside, and will touch pawl and strut, making valve jacket 3 and isolating switch touch pawl joins, thereby make to touch pawl, conducting rod, valve jacket 3, contact of breaker formation loop, again the extension line of detecting device is connected with U-shaped metal frame 5, can detects with the situation that contacts of contact of breaker conducting rod.
