Abstract
The utility model discloses a kind of pressing plate for electric power system control circuit and is in lockout when moving back fortune state, the pressing plate is to be plugged on circuit to connect on bottom plate, circuit connects bottom plate and is equipped with make contact and non-switched contact, the lockout includes insulation lid, insulation lid is equipped with the pressing plate groove to match with pressing plate and connects two bottom plate grooves that the two ends of bottom plate match with circuit, when pressing plate, which is inserted in circuit, connects the non-switched contact position of bottom plate, the pressing plate groove for the lid that insulate is covered on pressing plate, the two ends that circuit connects bottom plate are stuck on two bottom plate grooves.When pressing plate, which is in, moves back fortune state, pressing plate is covered using the utility model lockout, you can realize the purpose of block, personnel can be effectively prevent to it miscarry into operation during the work time.
Description
Technical field
The utility model is related to a kind of circuit pressing plates to control tool, specifically a kind of pressure for electric power system control circuit
Plate is in lockout when moving back fortune state.
Background technology
According to the requirement of electric system anti-accident measures, in the control loops such as " pressure release is tripped " of main transformer relay protection
Pressing plate it is reliable out of service, also in maintenance repair work, the pressing plate in the control loops such as " unsuccessful reason " is in check man
It is also temporarily reliable out of service during work, that is, throw to non-conducting state, and configuration use is the widest in protection screen at present
General is JL02-2 type pressing plates, and production and assembly technique is special, and neat appearance is conveniently operated；But when such pressing plate needs face
When or it is permanent when reliably exiting, scene can not to ensure safety be exited by removing the metal connecting sheet component of pressing plate, can not
Achieve the purpose that disconnecting circuit in a manner of dismantling pressing plate back side wiring.Due to such pressing plate in relay protection of power system screen
It is more, when some pressing plates need out of service, if there is staff is accidentally thrown again to on-state, may result in
Industrial accident occurs.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of pressing plates for electric power system control circuit to be in
Lockout when fortune state is moved back, when operating personnel throw pressing plate to after moving back fortune state, the pressing plate is covered using this lockout,
It is blocked, personnel can be effectively prevent to it miscarry into operation during the work time.
The utility model solves above-mentioned technical problem with following technical solution：
The utility model is in lockout when moving back fortune state for the pressing plate of electric power system control circuit, and the pressing plate is
It is plugged on circuit to connect on bottom plate, circuit connects bottom plate and is equipped with make contact and non-switched contact, and the lockout includes exhausted
Edge lid, insulation lid are equipped with the pressing plate groove that matches with pressing plate and connect what the two ends of bottom plate matched with circuit
Two bottom plate grooves, when pressing plate, which is inserted in circuit, connects the non-switched contact position of bottom plate, by the pressing plate groove cover for the lid that insulate
On pressing plate, the two ends that circuit connects bottom plate are stuck on two bottom plate grooves.
The insulation lid is made of transparent material, and warning-sign is pasted in the inside insertion of insulation lid or outside
Know.
The utility model lockout has the following advantages that：
1, it is made of transparent insulation material, it is ensured that the security isolation of energized circuit；
2, while ensuring safety, the fool proof possibility of field personnel can be greatly improved；
3, the utility model is simple in structure, is conveniently operated, and sticks police on the outside of embedded or lid on the inside of the transparent insulation lid
After the anti-misoperation mark for the property shown, visual effect is more obvious, and anti-misoperation is stronger.
Description of the drawings
Fig. 1 is the use that the utility model is in lockout when moving back fortune state for the pressing plate of electric power system control circuit
State diagram.
Fig. 2 is the schematic rear view of insulation lid in Fig. 1.
In figure：
1：Insulate lid, 1-1：Pressing plate groove, 1-2：Base groove, 2：Pressing plate, 3：Circuit connects pedestal, 3-1：It is non-switched
Contact, 3-2：Make contact.
Specific implementation mode
The utility model will be further described below in conjunction with the accompanying drawings：
On the circuit control circuit of normal operation, the inserting column of pressing plate 2 is inserted into the make contact that circuit connects pedestal 3
On 3-2, i.e., circuit control circuit is on-state, and also referred to as put into operation state.
When needing to cut off circuit control circuit, that is, needs pressing plate being switched to when moving back fortune state, the inserting column of pressing plate 2 is inserted
On the non-switched contact 3-1 that circuit connects pedestal 3 (i.e. non-switched position), the utility model lockout is then covered on into pressure again
On plate 2, as shown in Figure 1.
The utility model lockout includes transparent insulation lid 1, and insulation lid 1 is equipped with the pedestal to match with pressing plate 2
The groove 1-1 and two base groove 1-2 to match with the two ends of pedestal 3.Pedestal 3 is connected when pressing plate 2 is inserted in circuit
(be switched to when non-conduction position and move back fortune state), by insulate lid 1 pressing plate groove 1-1 cover on pressing plate 2, pedestal 3 it is upper
End angle and lower end angle are stuck on two base groove 1-2, by using the utility model lockout, can effectively prevent operator
Circuit is missed making operation by member.
The insulation lid 1 is made of transparent insulation material, and warning is sticked in the 1 inside insertion of insulation lid or outside
Anti-misoperation mark after, visual effect is more obvious, and anti-misoperation performance is stronger.
Claims (2)
1. the pressing plate for electric power system control circuit is in lockout when moving back fortune state, the pressing plate is to be plugged on circuit to connect
On logical bottom plate, circuit connects bottom plate and is equipped with make contact and non-switched contact, which is characterized in that the lockout includes insulation
