Description
Technical field
The utility model relates to the verification field of current transformer in the electric energy metrical, particularly a kind of goat's horn formula current transformer proving installation.
Background technology
Current transformer is installed in the power circuit metering secondary, and it is in service should to satisfy " error that records under the predetermined electric current value satisfies the error limit value of rules regulation ".Therefore, current transformer need carry out error testing to it before installation or behind the operation certain hour.
At present, the general employing of low-voltage current mutual inductor has two kinds of goat's horn formula and punchings.Straight-through current transformer is very convenient when error testing, many can be through in the p-wire at every turn and test simultaneously, to raise the efficiency.But, for 40% left and right sides goat's horn formula current transformer that accounts for total amount at present, singly only test, efficient is low, and under traditional mode, it once passes in and out line and adopts jointing clamp to connect testing power supply, because the primary side contact area of jointing clamp and current transformer is little, cause test to can't find test point for a long time fully, lose time; In addition, when high-current test the test duration long, cause testing apparatus, current transformer, p-wire heating, cause the threat of the person and device security.
Summary of the invention
The purpose of this utility model is to provide a kind of goat's horn formula current transformer proving installation, can connect easily, and test many goat's horn formula current transformers simultaneously, and efficient height, security is good.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of goat's horn formula current transformer proving installation, it is characterized in that, comprise support, be arranged on the front and back two row's tagblocks on the support, array pitch is identical with the spacing of the once lead-in wire of goat's horn formula current transformer, stagger mutually about different rows' tagblock, each tagblock is provided with two connection terminals of electrical connection.
Further improvement of the utility model and characteristics are:
Described tagblock comprises the collets that are fixed on the support and is fixed on conduction copper billet on the collets, and connection terminal is made up of the line pressing bolt that is used to place the outside rectangular channel of opening that goat's horn formula current transformer once goes between and be arranged on the rectangular channel upper wall that is opened in conduction copper billet two ends.
Described collets adopt epoxide resin material to form.
Described support foot is provided with universal wheel.
In the utility model, two row's tagblocks on support, array pitch is identical with the spacing of the once lead-in wire of goat's horn formula current transformer, and different rows' tagblock staggers mutually, and each tagblock is provided with two connection terminals of electrical connection; Two connection terminals on the same tagblock connect one of different goat's horn formula current transformers once lead-in wire respectively, and another of different goat's horn formula current transformers once goes between and connect a connection terminal of the adjacent tagblock of another row respectively; Like this, can realize easily that a plurality of goat's horn formula current transformer primary sides connect successively, improve the efficient of test.Simultaneously, tagblock is formed by being fixed on collets on the support and the conduction copper billet that is fixed on the collets, and connection terminal conducts electricity the line pressing bolt that is used to place the outside rectangular channel of opening that goat's horn formula current transformer once goes between and be arranged on the rectangular channel upper wall at copper billet two ends and forms by being opened in; Like this, during test the electrical connection of goat's horn formula current transformer reliable, contact area is big, security is good.

Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, be a kind of goat's horn formula current transformer proving installation of the present utility model.Wherein, tagblocks 2 are arranged in the front and back two that are provided with on the support 1, and array pitch is identical with the spacing of the once lead-in wire of goat's horn formula current transformer, and different rows' tagblocks about 2 stagger mutually, and each tagblock 2 is provided with two connection terminals of electrical connection.In the present embodiment, in order to save material, be respectively arranged with the tagblock with a connection terminal at the two ends at front row, also can use the tagblock with two connection terminals to replace certainly, all the other tagblocks are the tagblock with two connection terminals.
Tagblock comprises collets that are fixed on the support and the conduction copper billet 22 that is fixed on the collets 21, said fixing all adopts bolt to connect, be specially shown in the part of the partial cutaway among Fig. 1: collets adopt epoxide resin material to make, offer stepped hole on the collets, bolt head is sunken in the stepped hole to realize the insulation of bolt head.
With reference to Fig. 4, Fig. 5, be another kind of goat's horn formula current transformer proving installation of the present utility model, be with the difference of Fig. 1, Fig. 2, a kind of goat's horn formula current transformer proving installation shown in Figure 3: the foot of (1) support 1 is equipped with universal wheel 3, and convenient one is logical; (2) connection terminal is made up of the line pressing bolt that is used to place the outside rectangular channel of opening that goat's horn formula current transformer once goes between and be arranged on the rectangular channel upper wall that is opened in conduction copper billet 22 two ends.Before and after 12 goat's horn formula current transformer LH are connected across two rows about on the tagblock 2 that staggers, forms a series loop, make things convenient for and once test 12 goat's horn formula current transformer LH simultaneously.
