Abstract
A kind of protection exit attachment device of tape light; including two metal screws (1) side by side, two conducting bolts (2) being connected on two metal screws, it is arranged with insulating resin set respectively outside metal screw and conducting bolt；Protection connection sheet (3) made of conductive metal sheet is connected between two metal screws；Protection connection sheet is the openable and closable live metal piece in one end, and live metal on piece is equipped with insulating resin operating sheet (4)；It is connected with insulator foot (5) between two metal screws, is equipped with indicator light (6) on insulator foot, the electronic circuit board (7) being electrically connected with indicator light (6) is installed in insulator foot bottom surface.The utility model prevents accident by the indicator light instruction protection connection sheet both ends heteropolarity current potential with circuit board, will not make circuit breaker trip.Using the utility model, when operation, no longer needs to carry the special test equipments such as multimeter, can greatly improve safety and the operating efficiency of operation.
Description
Technical field
The utility model belongs to the converter station protective device technical field of substation, D.C. high voltage transmission.
Background technique
Running substation, D.C. high voltage transmission converter station protective device maintenance when need to exit jump outage
The connection sheet of road device needs to confirm that the contact of protective device exit relay is not bonded to together after protecting maintenance
When, the protection connection sheet can be put into.Otherwise, high-voltage circuitbreaker can be caused to trip, causes high-power, important load to disappear, gives
National economy and people's lives and properties bring heavy losses.
For this reason, it may be necessary to have a kind of instruction device that can indicate protection exit relay bonding, to prevent from connecting in measurement protection
When contact pin, because electric potential method is incorrect, the low, DC earthing of meter internal resistance etc. causes accident.
Summary of the invention
The purpose of utility model device is exactly to meet current production requirement, and the protection exit for providing a kind of tape light connects
Contact pin.
The purpose of utility model is achieved through the following technical solutions.
A kind of protection exit attachment device of tape light including two metal screws side by side, is connected to two
Two conducting bolts on metal screw, are arranged with insulating resin set respectively outside metal screw and conducting bolt；In two gold
Belong to and is connected with protection connection sheet between screw rod；The protection connection sheet is made of conductive metal sheet, is the openable and closable activity in one end
Sheet metal, the live metal piece one end are sleeved on a metal screw by sets of holes, and the other end is installed on separately by open slot
On a piece metal screw, insulating resin operating sheet is fitted in live metal piece；It is connected between two metal screws absolutely
Edge pedestal is equipped with indicator light on insulator foot, the electronic circuit board being electrically connected with indicator light is equipped in insulator foot bottom surface.
Under normal circumstances, protect one end of connection sheet negatively charged, the other end is not charged, illustrates to protect and does not start, can be with
Investment protection connection sheet；If indicator light is bright in operation, illustrate protection exit, operation such case occurs, cannot put into
Connection sheet is protected, otherwise may make running high-voltage circuitbreaker tripping or high-voltage dc transmission electric locking, cause heavy losses.
The utility model prevents accident by the indicator light instruction protection connection sheet both ends heteropolarity current potential with circuit board
Occur.Its indicator light can indicate that the danger signal of protection exit relay tip bonding, without making circuit breaker trip.This
Outside, after using the utility model, when operation, no longer needs to carry the special test equipments such as multimeter, can reduce the negative of operator
Load, greatly improves safety and the operating efficiency of operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the bottom view of Fig. 1；
Fig. 3 is the schematic top plan view for protecting connection sheet.
Specific embodiment
As shown in Figure 1 and Figure 2, the protection exit attachment device of tape light, including two metal screws 1 arranged side by side,
Two conducting bolts 2 being connected on two metal screws, are arranged with insulation respectively outside metal screw and conducting bolt
Resin set.Protection connection sheet 3 is connected between two metal screws, the protection connection sheet is as shown in figure 3, by conductive metal
Piece is made, and is the openable and closable live metal piece in one end, which is sleeved on a metal screw by sets of holes, 3a
On, the other end is installed on another metal screw by open slot 3b, is fitted with insulating resin operation in live metal piece
Piece 4, electric shock when preventing operator's operant activity sheet metal.It is connected with insulator foot 5 between two metal screws, is being insulated
Pedestal is equipped with indicator light 6, and the electronic circuit board 7 being electrically connected with indicator light 6 is equipped in insulator foot bottom surface, only needs low current
LED light can be made to glisten.As long as there is the DC voltage greater than 100V between the conducting bolt 2 at protection 3 both ends of connection sheet,
LED light will glisten, instruction protection exit relay tip bonding.When protecting connection sheet 3 to open, two conducting bolts
Between just disconnect, when protection connection sheet 3 is put into, be switched between two conducting bolts.If having between two conducting bolts heteropolar
Property current potential, indicator light will glisten, and since electric current is minimum, breaker will not trip.
The utility model internal resistance is not less than 10M Ω, and input capacitance is not more than 100pF, flash frequency 5Hz, internal resistance and input
Equivalent capacity is superior to now widely used digital multimeter.
