Abstract
A general high-voltage metering cabinet. The incoming line room, the metering room and the instrument room are connected to form an independent closed compartment, the incoming line sensor is installed on a fixing frame of the incoming line room, the incoming line electrified display is installed on a door of the incoming line room, the requirement of an electric power professional metering management department on independent closed management of a metering mutual inductor is met, meanwhile, before a breaker is not switched on, an incoming line power supply enters from the incoming line side, the incoming line electrified display displays electricity, and after the breaker is switched on, the incoming/outgoing line electrified display displays electricity, so that the electricity utilization reliability is met. The outlet chamber and the insulating plate are connected to form an independent compartment, the outlet sensor is installed on a fixing frame of the outlet chamber, and the outlet electrified display is installed on a door of the outlet chamber, so that the requirements of convenience for maintenance of a user and safety and reliability of installation and power utilization are met. The advantage is, rational in infrastructure, and the box is inside to be arranged compactly, and the box is small, save material, reduces area.
Description
Technical Field
The utility model relates to a general type high-pressure measurement cabinet, especially new forms of energy electricity generation high-pressure measurement cabinet such as photovoltaic, wind-powered electricity generation.
Background
At present, design schemes of high-voltage metering cabinets are uniform, but due to the rise of new energy industries (photovoltaic, wind power and the like), high-voltage metering cabinets produced by various manufacturers according to typical design of national grids and self production conditions are different, such as electrical schemes, external dimensions, structural forms, connection processes and the like of the high-voltage metering cabinets. Because the special characteristics of the photovoltaic power generation new energy are that the outgoing line side is the incoming line side of the commercial power, and the outgoing line side is also the incoming line side of the photovoltaic power generation new energy, the possibility of reverse power transmission exists, and personnel and equipment can be damaged if the operation and the judgment are wrong.
Disclosure of Invention
The utility model aims to solve the above-mentioned current problem that exists, provide an electric scheme reasonable, rational in infrastructure, the box is inside to be arranged compactly, and the box is small, save material reduces area's general type high-pressure measurement cabinet.
The utility model discloses a realize like this: the incoming line room, the metering room and the instrument room are connected to form an independent closed compartment, the incoming line sensor is installed on a fixing frame of the incoming line room, the incoming line electrified display is installed on a door of the incoming line room, the requirement of an electric power professional metering management department on independent closed management of a metering mutual inductor is met, meanwhile, before a breaker is not switched on, an incoming line power supply enters from the incoming line side, the incoming line electrified display displays electricity, and after the breaker is switched on, the incoming/outgoing line electrified display displays electricity, so that the electricity utilization reliability is met. The outlet chamber and the insulating plate are connected to form an independent compartment, the outlet sensor is installed on a fixing frame of the outlet chamber, and the outlet electrified display is installed on a door of the outlet chamber, so that the requirements of convenience for maintenance of a user and safety and reliability of installation and power utilization are met.
The utility model has the advantages that the installation sensor and the electrified display help the operator to prompt or confirm to a great extent in the visual cognition, whether the circuit is electrified or not can play a role before power transmission, in operation and in maintenance, because the incoming and outgoing lines of the photovoltaic new energy high-voltage metering cabinet are all possible to be electrified, the installation sensor and the electrified display are only arranged at the incoming line side, so that the operator is easily misled to neglect the safety consideration of the return power transmission at the line side, and safety accidents are caused. And the sensor and the electrified display are only arranged on the incoming line side of the traditional high-voltage metering cabinet, and the outgoing line side of the photovoltaic new energy high-voltage metering cabinet is the incoming line side of the traditional high-voltage metering cabinet, so that the sensor and the electrified display are arranged on the incoming and outgoing lines on the premise of not changing the structural form of the traditional metering cabinet, and therefore, if the use of the high-voltage metering cabinet is determined, only the corresponding parts need to be changed, and certain interchangeability is achieved.

fig. 4 is a cross-sectional view taken along line C-C of fig. 1.
The reference numerals in the drawings are as follows:
the system comprises a 1-incoming line chamber, a 2-outgoing line chamber, a 3-metering chamber, a 4-instrument chamber, a 5-incoming line sensor, a 6-outgoing line sensor, a 7-insulating plate, an 8-incoming line electrified display and a 9-outgoing line electrified display.
Detailed Description
The following detailed description is made with reference to the accompanying drawings: as shown in the figure, inlet wire room 1, measurement room 3, instrument room 4 are connected and are constituted independent confined compartment, inlet wire sensor 5 is installed on inlet wire room 1's mount, inlet wire electrified display 8 is installed on inlet wire room 1's door, satisfy the requirement of the electric power specialty measurement management department to the independent closed management of measurement mutual-inductor, before the circuit breaker did not close a floodgate simultaneously, the inlet wire power got into by the inlet wire side, inlet wire electrified display 8 shows there is the electricity, the circuit breaker is closed a floodgate after, the electrified display of inlet/outlet wire all shows there is the electricity, satisfy the power consumption reliability. The outlet chamber 2 and the insulation board 7 are connected to form an independent compartment, the outlet sensor 6 is installed on a fixing frame of the outlet chamber 2, the outlet electrified display 9 is installed on a door of the outlet chamber 2, the maintenance of convenience for users is met, the safety and the reliability of installation and power utilization are achieved, meanwhile, the breaker can be used for feeding wires upwards and feeding wires downwards, and the electrified displays are added on the inlet/outlet wires, so that the high-voltage metering cabinet can be used for power transmission lines and power generation lines, and the universality of the equipment is integrally improved.
