Description
Technical field:
The utility model relates to a kind of 35kV, 10kV switch cabinet bus Special grounding device
, be applied to 35kV, 10kV switch cabinet bus power failure ground connection in transformer substation high voltage chamber, belong to substation equipment maintenance and repair site technology field.
Background technology:
Electric power system high-voltage earthing device be in order on the equipment had a power failure and circuit due near close on the important tool ensureing staff's life security when voltage surprisingly appears in electrified body electrostatic induction or false switching.The operation principle of high-voltage earthing device is directly connected with the earth by earth terminal; once equipment or circuit are sent a telegram here suddenly; big current is directly introduced the earth by earthing device, and the big current simultaneously produced makes the rapid action of protective device, thus plays the effect of protection staff.
High-voltage earthing device can be divided into according to environment for use: indoor bus bar type earthing device and outdoor line type earthing device.What use in 35kV, 10kV hyperbaric chamber is indoor bus bar type earthing device.Indoor bus bar type earthing device mainly compression joint type earthing device, the hanging-connecting earthing device used in current 35kV, 10kV hyperbaric chamber, the earthing device of this two type must carry out reliable ground on exposed conductor, but switch cabinet bus is equipped with insulating sleeve more directly cannot install earth connection additional, brings inconvenience to busbar grounding.Also have a kind of use of earth handcart for switch cabinet bus grounding provides effective means, but due to the single and limited amount of the earth handcart model of configuration, and the switch cabinet equipment of each transformer station is not quite similar, and therefore earth handcart application is not extensive.In routine work, staff often utilizes the principle that PT handcart (isolating switch) is directly connected with bus, after the pull-out of PT handcart, by earth connection, the bus bar side fixed contact (column type) sent in PT cabinet realizes busbar grounding, but in current existing compression joint type, hanging-connecting earth connection and switch cubicle, fixed contact can not reliable contacts, so just brings potential potential safety hazard to the work on bus.
Utility model content:
The purpose of this utility model is to overcome above-mentioned existing technical deficiency and provides a kind of structure simple, easy to use, highly versatile and safe and reliable 35kV, 10kV switch cabinet bus Special grounding device.
The purpose of this utility model can be reached by following measure: a kind of 35kV, 10kV switch cabinet bus Special grounding device, it is characterized in that it comprises a pair insulating bar in relative rotation that be symmetrical and that linked together by connecting axle and holddown spring, the bottom of each insulating bar is equipped with insulated handle, the front portion of each insulating bar is equipped with the insulation clamping head of hollow, insulation clamping head and insulating bar are connected as a single entity, Metal Contact face is all embedded with in each insulation clamping head, insulation clamping head is connected by holding screw with Metal Contact face, two Metal Contact faces are equipped with mutually corresponding arc groove, one end of earth connection binding post is connected with Metal Contact face, the other end of earth connection binding post connects earth connection.
The utility model can produce following good effect compared with the prior art: the puzzlement finding exposed earth point when the utility model effectively can solve switch cabinet bus grounding, avoids staff and opens the potential safety hazard that bus insulation sheath produces.It has:
1. structure is simple, easy to use, safe and reliable.The utility model is horizontal compression type, coordinates closely, not easily loosen with fixed contact, makes to be connected between bus with earth connection in switch cubicle reliably, thus ensure that the personal safety of staff.
2. highly versatile.Be applicable to the switch cubicle of different manufacturers.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the A portion enlarged drawing of Fig. 3;
Embodiment:
Below in conjunction with accompanying drawing, preferred forms of the present utility model is elaborated:
Embodiment: a kind of 35kV, 10kV switch cabinet bus Special grounding device (see Fig. 1-Fig. 4), comprise a pair insulating bar 5 in relative rotation that be symmetrical and that linked together by connecting axle and holddown spring 4, the bottom of each insulating bar 5 is equipped with insulated handle 6, the front portion of each insulating bar 5 is equipped with the insulation clamping head 9 of hollow, insulation clamping head 9 and insulating bar 5 are connected as a single entity, Metal Contact face 1 is all embedded with in each insulation clamping head 9, insulation clamping head 9 is connected by holding screw 2 with Metal Contact face 1, two Metal Contact faces 1 are equipped with mutually corresponding arc groove 7, one end of earth connection binding post 3 is connected with Metal Contact face 1, the other end of earth connection binding post 3 connects earth connection 8.Earth connection binding post 3 is for connection metal contact-making surface 1 and earth connection 8, and the reliable connection that holddown spring 4 is Metal Contact face 1 and fixed contact provides necessary pressure; Metal Contact face of the present utility model contacts more firm with the fixed contact in switch cubicle, contact area is larger.
