Description
Technical field
The utility model relates to technical field of electric power, especially a kind of switchgear of safe and reliable operation.
Background technique
Smart grid has become the following power network development trend, China's power grid also realize from traditional power grid to it is efficient, economical,
The upgrading and leap of the modern power network of intelligence.Important component of the medium voltage switchgear equipment as smart grid, demand are all with day
Increase, to its safety and reliability, higher requirements are also raised.
In order to prevent and control potential accident of power supply, (power failure) power failure outside the plan is reduced, we design and develop one
Group has the medium voltage switchgear equipment of the safe and reliable operation of temperature and arc light monitoring function.
Utility model content
The purpose of this utility model is that it is reasonable, safe and reliable to provide a kind of design in place of making up the deficiencies in the prior art
The switchgear of operation.
The purpose of this utility model is realized by following technological means:
A kind of switchgear of safe and reliable operation, including switchgear, it is characterised in that: in the end for being also easy to produce high temperature
Interior installing temperature sensor, the temperature sensor are embedded in temperature measurement nut, and the temperature measurement nut coaxial package is in the double of end
On hook bolt；Temperature sensor connects temperature sampler by wireless signal, which is mounted in secondary meter room,
And it realizes and communicates with host computer；The door-plate of secondary meter room is equipped with the temperature indicator of display end real-time temperature.
Moreover, the switchgear is loop-network switch cabinet.
Moreover, a temperature sampler configures 16 road loop-network switch cabinets.
Moreover, further including optical sensor and arc light monitoring device, optical sensor is arranged on fibre-optical probe, and optical sensor passes through
Cable connection arc light monitoring device；Arc light monitoring device is mounted in secondary meter room, which connects breaker.
The advantages and positive effects of the utility model are as follows:
1, for switchgear in During Process of Long-term Operation, the positions such as the cable connection of switch is connected with bus can be because aoxidizing or contacting
Resistance is excessive and generates heat, and the temperature majority of these heating positions is unable to monitor, can not forecast, eventually leads to accident, very
To causing fire.Solving conductive body contact position problems of excessive heat thus is the key that prevent such accident to occur, and realizes that temperature exists
Line monitoring is to guarantee the requirement of the important means and smart grid of switchgear safe operation.
The utility model uses passive and wireless temperature monitoring mode, and temperature sensor connects temperature acquisition by wireless signal
Device, the temperature of key point in monitoring switch cabinet.The advantages of monitoring mode is: (1) temperature sensor uses passive induction mode,
It is driven without battery, no replacement is required battery.(2), without electrical connection between temperature sensor and temperature sampler, data are wireless
Transmission.To realize high_voltage isolation, equipment safety operation is ensured.(3) the transmission mode of this wireless and passive of is believed from surrounding
Number interference, be truly realized non-maintaining.
2, short circuit or insulation breakdown failure occur in switchgear, will lead to power failure, cause equipment damage and people
Member's injury.Short circuit or insulation breakdown failure are often associated with the appearance of electric arc, in order to avoid failure influences to expand, eliminate potential danger
Caused damp production reduces equipment damage, and the electrical equipment for this failure occur must be out of service as early as possible, exits electricity
Net.
The utility model is set by arc light monitoring mode, optical sensor by cable connection arc light monitoring device, monitoring power supply
Short circuit or insulation breakdown failure in standby.Arc light monitoring device issues trip signal immediately and gives after the arc light of detected arc failure
Breaker, so that the energy of breaking arc failure rapidly, protects operator's life security and equipment from destroying.

Specific embodiment
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 switchgear of safe and reliable operation, including switchgear 1, the switchgear are loop-network switch cabinet.Due to switch
Cabinet is well-known technique, its internal structure and connection relationship is not described in detail herein.
As shown in Figure 1, installing temperature in the end 2 for being also easy to produce high temperature on the basis of not influencing switch cabinet structure
Sensor 5, as shown in Fig. 2, temperature sensor is embedded in temperature measurement nut 10, double end of the temperature measurement nut coaxial package in end
On bolt 3.Temperature variations are transferred to temperature sampler 4 at any time, temperature sampler utilizes antenna emitting radio waves, this electricity
Wave one side activationary temperature sensor, while thermometric order is also transmitted, temperature sensor starts temperature measurement circuit upon activation, and will
Temperature-measuring results are sent to temperature sampler, and whole process is all digital protocol communication.
Temperature sensor be it is multiple, pass through wireless signal and connect temperature sampler, it may be assumed that temperature sensor is adopted with temperature
For storage without any electrical connection, the data interaction between them is transmitted by wireless signal, will not influence the insulating properties of system
Can, use is safer.Temperature sampler is mounted in secondary meter room 6, and (is stood by wired or wireless mode and host computer
End main frame and monitoring system) realize communication.
Meanwhile temperature indicator 8 being installed on the door-plate of secondary meter room, which connect with host computer,
To show end real-time temperature.One temperature sampler can configure 16 road loop-network switch cabinets, and temperature sampler connection is upper
Machine.In addition, the knot of a monitoring system (host computer) can be uploaded to using more temperature samplers when switchgear is multiple
Configuration formula, the Scalable mode of the more cabinets of a machine is not by switch cabinet structure and spacial influence.As shown in figure 4, being the survey of the more cabinets of a machine
Warm block diagram.
The utility model further includes optical sensor 9 and arc light monitoring device 7, and optical sensor is arranged on fibre-optical probe, and light passes
For sensor by cable connection arc light monitoring device, cable material is fibre-optic cable, i.e. optical fiber, when arc fault occurs, guarantees to exempt from
By any electromagnetic interference.Arc light monitoring device is mounted in secondary meter room, which connects breaker, arc light monitoring device
It is that common secondary line is connect with breaker.As shown in figure 5, being supervised using optical sensor to the arc light in loop-network switch cabinet
It surveys, once because short circuit or insulation breakdown produce arc light, after optical sensor quick detection, signal is transferred to arc light monitoring device, arc
After light detection device is judged, trip signal is issued to breaker, keeps its out of service, avoids failure state of affairs further expansion.
