Description
Technical field
The utility model relates to a kind of breakers of external voltage sensor.
Background technique
Currently, controller needs to acquire as national grid is higher and higher to line fault differentiation and the requirement of line loss calculation
Three-phase voltage is calculated for transmission power, need to acquire judgement of the residual voltage for fault direction, existing to be all made of electromagnetic type three
Phase voltage mutual inductor, the price height of such voltage transformer, volume are big and than heavier, and the individually designed mounting bracket of need is for pacifying
Dress wastes production cost and space occupied, therefore, has designed a kind of breaker of low, the light and small external voltage sensor of price
Through imperative.
Utility model content
The purpose of the utility model is to provide a kind of breakers of external voltage sensor, it is characterized in that breaker ABC tri-
It is mutually mounted on voltage sensor, exportable ABC three-phase voltage and residual voltage, has the characteristics that price is low, small in size and light.
To achieve the above object, the utility model provides the following technical solutions:
The breaker of a kind of external voltage sensor provided by the utility model, it is characterized in that: securing the stand to open circuit
On device shell, three voltage sensors are equally spacedly fixed on the base, pedestal is fixed on bracket, lower terminal plate is tight
Patch current transformer is fixed, and a conducting wire of voltage sensor is connected by line nose with lower terminal plate, by voltage sensor
Secondary wiring passes through pedestal and coil holder is fixed on inside junction box for breakers.
Conducting wire is cast in voltage sensor top, and outsourcing material uses silicon rubber.
The secondary wiring uses twisted-pair shielded wire.
Breaker provided by the utility model, ABC three-phase are mounted on voltage sensor, exportable ABC three-phase voltage and
Residual voltage, this breaker have the characteristics that price is low, small in size and light；Because of voltage sensor and breaker integrative installation technology,
Without individually designed mounting bracket to install voltage sensor, production cost and space occupied are saved, in-site installation is convenient for；Electricity
A conducting wire on pressure sensor directly passes through line nose and is connected with lower terminal plate, is not necessarily to staff's field connection, saves scene
Set-up time.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model breaker.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
In figure: 1, lower terminal plate 2, voltage sensor 3, current transformer 4, conducting wires 5, a line noses 6, breaker
Shell 7, terminal box 8, coil holder 9, bracket 10, pedestal 11, secondary wiring.
As shown in Figure 1, a kind of breaker of external voltage sensor of the utility model, it is characterized in that: bracket 9 is fixed
In circuit breaker housing 6, three voltage sensors 2 are equally spacedly fixed on pedestal 10, pedestal 10 is fixed on bracket 9
On, lower terminal plate 1 is close to current transformer 3 and is fixed, a conducting wire 4 of voltage sensor 2 is passed through into line nose 5 and lower terminal plate
1 is connected, and the secondary wiring 11 of voltage sensor 2 is passed through pedestal 10 and coil holder 8 is fixed on inside junction box for breakers 7.
Conducting wire 4 is cast in 2 top of voltage sensor, and outsourcing material uses silicon rubber.
The secondary wiring 11 uses twisted-pair shielded wire.
Breaker provided by the utility model, ABC three-phase are mounted on voltage sensor 2, exportable ABC three-phase voltage and
Residual voltage, this breaker have the characteristics that price is low, small in size and light；Because of voltage sensor 2 and breaker integrative installation technology,
Without individually designed mounting bracket to install voltage sensor 2, production cost and space occupied are saved, in-site installation is convenient for；
A conducting wire 4 on voltage sensor 2 is directly connected by line nose 5 with lower terminal plate 1, and staff's field connection, section are not necessarily to
Save field installation time.
