Abstract
The utility model discloses a relay protection secondary circuit test device which comprises a box body, wherein a plurality of wiring terminals and a plurality of signal lamps are arranged on the box body; codes are formed on the signal lamps; the wiring terminals are connected with colorful test connection wires; the signal lamps, the wiring terminals and the colorful test connection wires are connected with one another in a one to one correspondence manner; a magnet is arranged on the back of the box body; and crocodile-shaped wire clamps are arranged at the tail ends of the colorful test connection wires. The codes are formed on the signal lamps, and nodes and circuit numbers which correspond to the signal lamps are marked on the codes, so that the crocodile-shaped wire clamps of the colorful test connection wires can pass through test wire passing holes of a protection screen and are connected to corresponding terminals of the nodes and the circuits which are to be checked on terminal rows in the protection screen; if the signal lamps are switched on, the test is successful; and due to a plurality of signals lamps, a plurality of wiring terminals and a plurality of colorful test connection wires, switch on and switch off of a plurality of nodes and a plurality of circuits can be detected at the same time.
Description
Technical field
The utility model belongs to technical field of relay protection, particularly a kind of relay protection secondary circuit proving installation.
Background technology
Raising along with economic development and living standards of the people; The need for electricity amount increases rapidly, improves protective device effectively and examines efficient surely, shortens the equipment power off time and becomes raising power system power supply reliability; Promote power supply service quality, increase the important means of effective delivery.Traditional test unit can only be checked one to two node or loop at every turn, Interventions Requested for a long time, the reaying protection test personnel must frequently disconnect line in protection screen, increased the wiring fault rate.In the process of the test, need the technician who cooperates many, numerous and diverse property of work also makes decides unavoidable generation omission in the inspection work; Few inspection; The phenomenon of duplicate test causes the defencive function test duration long, and final result is an inefficiency; The equipment power off time is long, can't meet the requirement of people to the reliable power supply of electric power enterprise.
The utility model content
The technical matters that the utility model solves just is to overcome the problems referred to above, and provide a kind of make a plurality of nodes and loop break-make situation realize monitoring, test result simultaneously accurately and reliably, test efficiency height, simple operation, stable performance and effective minimizing prevented the generation of mis-wired, effectively reduced the relay protection secondary circuit proving installation of power off time when frequently disconnecting line.
The technical scheme that purpose adopted that realizes the utility model is: a kind of relay protection secondary circuit proving installation; Comprise box body; Binding post and signal lamp are set on the said box body, on the said signal lamp coding are set, said binding post is connected with colored test connection; Said signal lamp, binding post and colored test connection connect one to one, and said signal lamp, binding post and colored test connection all are provided with several.
Said box body back is provided with magnet.
Said colored test connection end is provided with the crocodile wire clamp.
Because the utility model is provided with signal lamp, binding post and colored test connection that many groups are connected, and coding is set on the signal lamp, clear pairing node of signal lamp of coding subscript and loop numbering, like this
The test wire that the crocodile wire clamp of colored test connection is passed protection screen is through the hole, is connected in protection screen inner terminal row and goes up on the corresponding terminal in the node that needs check and loop, if signal lamp is bright; Just representative success of the test, a plurality of signal lamps and a plurality of binding posts that are connected and colored test connection can detect the break-make situation in a plurality of nodes and loop simultaneously, and pilot project is many when really having solved protective relaying device node and loop-around test; It is frequent to disconnect line, needs many people to cooperate, and causes a long operation difficult problem of defencive function test duration; Prevented that protective device from deciding omission in the inspection work; Few inspection, the generation of duplicate test phenomenon, and the back of device is provided with magnet; After the relay protection reviewer has fulfiled the work formality, utilize magnet this device to be adsorbed in the position of just observing above the protection panel that is verified protective device.Monitoring, test result were accurately and reliably when in a word, the utility model made a plurality of nodes and loop break-make situation, test efficiency height, simple operation, stable performance and effective minimizing prevented the generation of mis-wired, effectively reduced power off time when frequently disconnecting line.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the test philosophy figure of the utility model.
Embodiment
Like Fig. 1, shown in Fig. 2, a kind of relay protection secondary circuit proving installation; Comprise box body 1; Binding post 2 and signal lamp 3 are set on the said box body 1, on the said signal lamp 3 coding are set, said binding post 2 is connected with colored test connection 4; Said signal lamp 3, binding post 2 and colored test connection 4 connect one to one, and said signal lamp 3, binding post 2 and colored test connection 4 all are provided with several.Said box body 1 back is provided with magnet.Said colored test connection 4 ends are provided with crocodile wire clamp 5.
The utility model is provided with signal lamp 3, binding post 2 and the colored test connection 4 that many groups are connected, and on the signal lamp 3 coding is set, clear signal lamp 3 pairing nodes of coding subscript and loop numbering; The test wire that like this crocodile wire clamp 5 of colored test connection 4 is passed protection screen is through the hole, is connected in protection screen inner terminal row and goes up on the corresponding terminal in the node that needs check and loop, if signal lamp is bright; Just representative success of the test; A plurality of signal lamps and a plurality of binding posts that are connected and colored test connection can detect the break-make situation in a plurality of nodes and loop simultaneously, and pilot project is many when really having solved protective relaying device node and loop-around test, and it is frequent to disconnect line; Need many people to cooperate; Cause a long operation difficult problem of defencive function test duration, prevented that protective device from deciding omission in the inspection work, few inspection; The generation of duplicate test phenomenon; And the back of device is provided with magnet, after the relay protection reviewer has fulfiled the work formality, utilizes magnet this device to be adsorbed in the position of just observing above the protection panel that is verified protective device.
