Abstract

The utility model relates to a transformer protection outlet matrix check meter, which can solve the problems that the conventional alignment device is low in efficiency and many in repetition labors, the communication of detection personnel is troublesome, and the detection is easy to fail. The scheme is that an alignment circuit is arranged in a shell and comprises a power supply of which one end is connected with a plug wire port at one side of the shell via a conducting wire, a common end conducting wire is plugged in the plug wire port, and a switch arranged on the shell is in series connection between the power supply and the plug wire port; the other end of the power supply is in series connection with a buzzer of which the other end is in parallel connections with a plurality of light-emitting diode LEDs, and the light-emitting bodies of the light-emitting diodes are placed in fixing holes on the shell and extended out of the exterior of the shell; the upper end part of the shell is equipped with a plurality of plug wire ports in one-to-one correspondences and connected with the plurality of light-emitting diodes, each plug wire port is equipped with a conducting wire of which the end part is equipped with a clamping head. The connection of the power transformer protection outlet matrix check meter of the utility model and the connection outlet of a multi-core cable is simple, rapid and reliable, and the power transformer protection outlet matrix check meter is compact in overall structure, low in manufacturing cost, simple and convenient in use, easy in carrying and good in expansibility.

Description

A kind of power trans-former protection outlet matrix check appearance

One, technical field

The utility model relates to electric equipment, particularly a kind of power trans-former protection outlet matrix check appearance.

Two, background technology

Transformer is an extremely important power transmission and transforming equipment in the electric system, and it can convert a kind of electric energy of voltage into the electric energy of another kind of voltage, and main effect is a voltage of transformation, is beneficial to the transmission of power; On same section circuit, transmit identical power, voltage is after step-up transformer boosts, and the circuit electric current transmitted reduces; Can reduce line loss, improve and send electric economy, reach the purpose of long distance electricity, step-down then can be satisfied user's needs of each utmost point working voltage; The verification of tranformer protection is the power supply personnel guarantee the transformer safe operation at present through manual simulation test a important means, at present, at the electric power breach relatively under the serious situation, the Time Compression of transformer interruption maintenance very short; Such as the three side main-transformers of 220kV, power off time only 3-4 days, so just the verification to tranformer protection causes the time short; Task is heavy, and between turn(a)round, only tranformer protection tripping operation outlet MATRIX CHECK-UP will be done more than 100 time; This is concerning the relay protection staff, and the time is long, and conventional way is a kind of protection of every verification; All will measure each protection tripping operation with multimeter and export, in order to prevent to protect malfunction or tripping, having several tripping operations outlets all to want frequent doing to protect several times usually could finish tripping operation outlet measurement; Tranformer protection has 24-72 tripping operation outlet usually, and common every cover tranformer protection all has tens kinds of protections, and protection outlet MATRIX CHECK-UP is got off like this; Do more than 100 protection, repetitive operation is many, and amount consuming time is big.

Three, summary of the invention

To the problems referred to above; For solving the defective of prior art; The purpose of the utility model just provides a kind of tranformer protection outlet matrix check appearance, can solve effectively that existing alignment device efficient is low, the duplication of labour is many, the testing staff links up trouble and detect to be prone to the problem of failing.

The technical scheme of its solution is, comprises housing, and pair line circuit is arranged in the housing; Said line circuit is comprised power supply, an end of power supply links to each other through the plug wire port of lead with housing one side, plug-in mounting common port lead on the plug wire port; Connect between power supply and the plug wire port and be connected to the switch that places on the housing, the other end series connection of power supply is connected to hummer, and the other end of hummer also is connected with a plurality of LEDs; The luminophor of light emitting diode places in the fixed orifice on the housing, and stretches out outside, and there is plug wire mouth corresponding one by one with a plurality of light emitting diodes and that link to each other the housing upper end; A lead respectively is housed on each plug wire mouth, and chuck is equipped with in the end of lead.

The utility model is connected the outlet connection simply, rapidly, reliably with polycore cable, and the sign of target core is intuitively accurate, compact overall structure, and cost of manufacture is low, and is easy to use, is easy to carry about with one, and antijamming capability is strong, favorable expandability.

Four, description of drawings

Fig. 1 is the plan structure figure of the utility model.

Fig. 2 be the utility model to line circuit to the line principle assumption diagram.

Five, embodiment

Explain further details below in conjunction with the embodiment of accompanying drawing to the utility model.

Provided by Fig. 1, Fig. 2, the utility model comprises housing, and pair line circuit is arranged in the housing 1; Said line circuit is comprised power supply 2, an end of power supply 2 links to each other through the plug wire port 3 of lead with housing 1 one sides, plug-in mounting common port lead 4 on the plug wire port 3; Connect between power supply 2 and the plug wire port 3 and be connected to the switch 5 that places on the housing 1; The other end series connection of power supply 2 is connected to hummer 6, and the other end of hummer 6 also is connected with a plurality of LEDs, and the luminophor of light emitting diode places in the fixed orifice 7 on the housing 1; And stretch out housing 1 outside; There is plug wire mouth corresponding one by one with a plurality of light emitting diodes and that link to each other housing 1 upper end, and a lead 8 respectively is housed on each plug wire mouth, and chuck 9 is equipped with in the end of lead 8.

In order to guarantee result of use, said power supply 2 is dry cell or rechargeable battery.

Said housing is square hollow body, and having up and down, two parts constitute.

When the utility model uses,, and link to each other with detector common port lead 4 with the port one end short circuit of Devices to test; The hand-held check meter of testing staff is clamped in the positions such as contact CKn of the tranformer protection that needs to detect with a plurality of chucks 9., and when the CKn junction closure, check meter moment indicates the target outlet; The LED light of the light emitting diode in its formed a plurality of loops indicates its position through light; Hummer 6 is rung, and the indication transformer outlet is normal, so circulation; By the different transformer fault of testing crew simulation, the corresponding outlet of check matrix.

The utility model shows that through the connection situation of acousto-optic indicating device to cable core test is simple, rapid, reliable, has avoided revision test, is easy to carry about with one, and antijamming capability is strong, and favorable expandability, efficient can improve more than 5-7 times.
