Description
Technical field
The utility model is related to electrical equipment technical field, especially a kind of bracket mount type electric current suitable for switchgear
The mounting structure of mutual inductor.
Background technology
Switchgear is a kind of common electrical equipment, the main function of switchgear be generated electricity in electric system, transmitted electricity,
During distribution and electric energy are converted, electrical equipment is opened and closed, controlled and protected.Component in switchgear mainly has open circuit
Device, disconnecting switch, on-load switch, operating mechanism, mutual inductor and various protective devices etc..
User is when using switchgear, the case where being frequently encountered in an interval using double cables, since his sampling is mutual
Sensor is mounted on cable, thus needs to wear one group on every cable, two cables will wear two groups of mutual inductors, i.e.,：
There are tapered head, cable to be directly installed on tapered head, then fastened by clamp in the cable vault of cabinet, wears cable type electric current
Mutual inductor then needs two groups to wear cable type current transformer to be each passed through electricity on cable, when if it is double cables across cable suspension
Cable is suspended on cable.His current signal is composite value in this way, inaccurate, and cost is also higher, and installation is inconvenient.
Utility model content
The purpose of this utility model is that in place of making up the deficiencies in the prior art, provide one kind can improve measurement accuracy,
It saves cost and facilitates the mounting structure of the bracket mount type current transformer suitable for switchgear of construction and installation.
The purpose of this utility model is realized by following technological means：
A kind of mounting structure of bracket mount type current transformer suitable for switchgear, including cabinet and be mounted on cabinet
Interior electrical part, the multiple tapered heads of cable indoor location of cabinet, it is characterised in that：It is respectively mounted an electric current on each tapered head
Mutual inductor, the centre bore coaxial package of the current transformer on tapered head, each indoor all current transformers of cable
Pedestal is fastened by bolts on a mounting plate, which is made into integration by transverse slat and riser, current transformer
Pedestal be installed on transverse slat, which is connect by bolt with side cabinet.
Moreover, the center-hole diameter of the current transformer is than the existing diameter for wearing cable type current transformer centre bore
Greatly.
Moreover, having activity surplus between the riser and side cabinet.
The advantages of the utility model and good effect are：
1, the centre bore of current transformer used by the utility model is bigger than original cable type mutual inductor of wearing, and can be sleeved on
On the tapered head of switchgear, therefore one group of current transformer can also measure total electric current in double cables, this design can be substantially
Improve measurement accuracy.
2, the utility model is simple in structure, improvement is reasonable, facilitates construction and installation, has not both interfered with the entirety of existing switchgear
Pattern is distributed, and will not increase the use burden of staff, also saves cost.
3, the utility model is a kind of mounting structure of the bracket mount type current transformer suitable for switchgear, this structure
It is ingenious in design, solve the problems, such as tradition wear cable type current transformer using when exist, using measurement can be improved after this structure
Precision reduces use cost, provides facility for construction and installation, is especially suitable for using in the case of using double cables in an interval.
Description of the drawings
Fig. 1 is the front view (broken section) of the utility model；
Fig. 2 is the side view (broken section) of Fig. 1.
Specific implementation mode
Embodiment of the utility model will be described in detail below with reference to the attached drawings；It should be noted that the present embodiment is narrative
, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of mounting structure of bracket mount type current transformer suitable for switchgear, including cabinet 1 and be mounted on cabinet
Internal electrical part, since the structures such as cabinet and electrical part and connection relation are not related to innovating improvements, to its structure
Without repeating, the multiple tapered heads 4 of cable indoor location of cabinet are each respectively mounted a current transformer 2 on tapered head, should
The center-hole diameter (76mm) of current transformer greatly than the existing diameter (55mm) for wearing cable type current transformer centre bore, therefore
The centre bore coaxial package of current transformer is on tapered head.
The pedestal of the indoor all current transformers of each cable is securedly mounted to by bolt 5 on a mounting plate,
The mounting plate is the L-shaped structure being made into integration by transverse slat 3 and riser 6, has mounting hole on the pedestal of current transformer, logical with transverse slat
It crosses bolt to be fastenedly connected, riser reserves connecting hole, and connect with the side plate 8 of cabinet by bolt 7, and bolt cannot when connection
Fastening, makes it have movable surplus, i.e., has gap between riser and side cabinet, can be random when facilitating end to be inserted into
Adjust position.
The operation principle of the utility model is：
The centre bore of the current transformer used in the utility model is bigger than original cable type mutual inductor of wearing, and can cover in this way
There is mounting hole on tapered head, and in mutual inductor bottom, can be fastenedly connected by bolt with mutual inductor mounting plate, mutually
The side of sensor mounting plate is reserved connecting hole and is attached with side cabinet, and bolt cannot fasten when connection, so that it is had movable
Surplus, can arbitrarily adjust position when facilitating end to be inserted into, such one group of current transformer can also be measured in double cables
Total electric current can improve measurement accuracy, save cost, facilitate construction and installation.
