Abstract

The utility model relates to the technical field of electrical tests for nuclear power stations, and particularly discloses a relay protection checking table. All relay protection devices are mounted intensively in the form of a workbench, and working personnel only need to plug corresponding connecting terminals correspondingly in the form a terminal strip and plug corresponding devices to be checked correspondingly in the form of a slot. The utility model has convenient operation, high security, and high reliability, thereby reducing possible accidents of the equipment due to improper handling during checking, efficiently saving the cost, and increasing the safety factors.

Description

The relay protection checking table
Technical field
The utility model belongs to nuclear power station electrical test technical field, is specifically related to a kind of relay protection checking table.
Background technology
The used relay of nuclear power station protection system mostly is the plug-in device, and is of a great variety.During each overhaul, the annual verification work of many relays is carried out because of being subjected to limitation of field condition need tear open in testing laboratory, each work all will be carried out wiring by the shell to relay in testing laboratory, and original in the testing laboratory what dispose is common worktable, layout during verification is limit by condition not to be quite reasonable, work simultaneously (more often taking place in the overhaul) in case carry out a plurality of working groups, can the phase mutual interference.And used relay dc supply has only one, during the work of many groups, can only draw the working power line temporarily, and is also dangerous.Especially in auxiliary diesel engine system, 500KV and the 220KV GIS control system, a large amount of auxiliary reclays is all arranged, the repair time that each overhaul is arranged is all shorter, original verification mode all is directly test wire to be connected on the relay pin, because quantity is more, each wiring process all can have been spent a large amount of working times, and it is careless slightly at work, just might cause the test connection short circuit, might damage relay or calibration equipment, also be a kind of danger side of body to personal safety.
Therefore the relay protection checking table that needs a kind of relay protection work of suitable nuclear power station.
Summary of the invention
It is a kind of rationally distributed that the purpose of this utility model is to provide; the loop is clear and intuitive; easy to operate relay protection checking table; the work quality of the verification work of protective relaying device is effectively controlled, work efficiency effectively improves; the security of whole verification work is effectively ensured, and easy to operate.
The technical solution of the utility model is as follows:
A kind of relay protection checking table, it comprises the relay protection tester, dc supply and worktable, it is characterized in that: described worktable comprises the work facade on work box and the work box, this work box facade is the rectangle facade, and the work facade is provided with the dc switch that is connected with dc supply, by calibration equipment slot, the terminal row that connection terminal can be installed and AC socket; Described work box is a rectangle; be provided with two; be separately positioned on the work facade about the below; be provided with rectangular drawer between two work boxs; described dc supply and relay protection tester are separately positioned in the work box of the left and right sides, and the relay protection tester is connected with outside 220V power supply by AC socket.
In above-mentioned relay protection checking table: be provided with drawer on the described work box, place dc supply and relay protection tester in the drawer.
In above-mentioned relay protection checking table: described work box is made up of two-layer drawer up and down.
Described work box is provided with isolation mesa.
The beneficial effects of the utility model: adopt the form of worktable that all protective relaying devices are installed concentratedly; and adopt the form of terminal row; the staff only needs the corresponding plug of connection terminal with correspondence; adopt the form of slot, the staff only need with correspondence by the corresponding plug of calibration equipment, handled easily; safe, reliability is high; reduced in the verification work because of the issuable unexpected injury of misoperation, effectively saved cost, also improved safety coefficient equipment.
Description of drawings
Fig. 1 is the principle of work synoptic diagram of relay protection checking table;
A kind of relay protection checking table synoptic diagram that Fig. 2 provides for the utility model;
Among the figure: 1. relay protection tester; 2. dc supply; 3. drawer; 4. isolation mesa; 5. AC socket; 6. work box; 7. work facade; 8. dc switch; 9. by the calibration equipment slot; 10. terminal row; 11. drawer.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Protective relaying device schematic diagram as shown in Figure 1; relay protection tester 1 by connection terminal be connected by calibration equipment; dc supply 2 and air switch is installed between the calibration equipment, relay protection tester 1 is connected with outside 220V power supply by AC socket 5.
Relay protection checking table structural representation as shown in Figure 2, worktable comprises the work facade 7 on work box 6 and the work box 6, described dc supply 2 and relay protection tester 1 are arranged in the drawer 11 of work box 6; Work facade 7 be provided with the dc switch 8 of dc supply 2, by calibration equipment slot 9, the terminal row 10 that connection terminal can be installed and AC socket 5.Work box 6 has two, is installed in 7 times left and right sides of work facade respectively, and two drawers 3 are installed between the work box 6, is used for placing related tool and meter.About two tool boxes can be designed to two-layer drawer up and down, upper strata drawer shelf test line, lower floor places dc supply 2 and relay protection tester 1 respectively.
The shell of all detachable protective devices is all installed concentratedly on a worktable; and the distribution of all devices is caused the terminal row 10 on the work facade 7 of protection platform; make things convenient for wiring and control; and for each device has all disposed the dc switch 8 that works alone, even a people also can conveniently operate.The staff only needs protective device is put into corresponding shell, and corresponding wiring gets final product on connecting terminal block then, the operation intuitive and convenient.
One cover checking table is made up of two identical checking tables of size, and two working groups can carry out the work simultaneously.
For guaranteeing the personal safety in the verification work, on work box 6, place isolation mesa 4; Checking table configuration ground terminal links to each other with effective grounding point in the factory building.
Each checking table all disposes an adjustable direct supply of WLV-III type, and power range is 0-300V, and rating of set 200W can satisfy the demand that a plurality of relays are worked simultaneously.
All distributions all use line directly to be not less than the flame retardant cable of 2.5mm, used testing terminal jack is fit to continue and protects special-purpose 4mm test wire plug, the different color of testing terminal configuration is to make things convenient for wiring (according to the power industry custom, that corresponding A, B, C, N are respectively is yellow, green, red, black terminal etc.).
