Description
Technical field
The utility model relates to a kind of high-tension switch cabinet supervising device, and particularly a kind of switch cubicle temperature and humidity monitor and are used for contact humiture in the sense switch cabinet, switch cubicle ambient temperature and switch cabinet state demonstration.
Background technology
High-tension switch cabinet is a very important electric equipment in the electric power system.Because a variety of causes; Cause that thereby the switch cubicle running status worsens the initiation electric power system and breaks down; Therefore the running status of switch cubicle is carried out on-line monitoring, find that in time potential faults makes prediction to the cumulative bad fault, for the normal operation that guarantees switch cubicle; Reduce maintenance frequency, the operational reliability and the automaticity that improve electric power system are all significant.High-tension switch cabinet is under certain temperature and humidity long-time running situation, and the contact resistance of contact maybe be because of the temperature rise accelerated oxidation, and oxidation results causes contact resistance value to increase, and impels heating to strengthen so again, and temperature raises, even the starting the arc is burnt.This process is often comparatively hidden, and time of origin is very short, has led to a lot of serious accidents over the years.The effective measures of avoiding this type of accident to take place are real-time monitoring contact working temperature and humidity.
Prior art is to high-tension switch cabinet difference installment state display system and contact humiture observation system.
Existing contact humiture observation system generally comprises electric supply installation, and plurality of contacts is measured temperature sensor, plurality of contacts humidity measuring transducer, ambient temperature and humidity transducer, control board, humiture Displaying Meter, repeater and main website software eight parts and formed.
The electricity getting device of contact temperature measurement provides electric energy for part hardware; Contact is measured the temperature that temperature sensor carries out real-time measuring contacts surface; Contact humidity measuring transducer carries out contact surface humidity; Ambient temperature and humidity is measuring switch cabinet temperature inside and humidity, and they upload to the temperature and humidity signal of obtaining on the display list through lead or wireless technology, are handled by control board.Handling the back shows on display list; And with the data upload on the different switch cubicles to relay station; Relay station upload the data to main website through lead or wireless transmission, deposits system database after main website analyzes through daemon software in and waits for that the staff checks and controls.Contact humiture monitoring of structures block diagram can be with reference to the block diagram of existing humiture observation system shown in Figure 1.
Existing switch cabinet state display unit generally comprises electric supply installation, some on off state analysis circuits, ambient temperature and humidity transducer, control board, temperature and humidity control circuit, on off state display floater, repeater and main website software eight parts and forms.
The electric supply installation of switch cabinet state display unit provides electric energy to hardware, and the on off state analysis circuit is to analyze the inner state of switch cubicle, through lead or wireless uploading on the control board, is handled by microprocessor, carries out Temperature and Humidity Control or warning after the processing.After the processing gained data are shown on the on off state display floater of switch cubicle; And with the data upload on the different switch cubicles to relay station; Relay station upload the data to main website through lead or wireless technology, deposits system database after main website analyzes through daemon software in and waits for that the staff checks and controls.Switch cabinet state display device structure block diagram can be with reference to the block diagram of existing switch cabinet state display unit shown in Figure 2.
Above-mentioned these two systems have several partial functions similar; If must adopt two to overlap independently system according to prior art; And have no contact between the system, such two systems use together just makes that hardware cost, R&D costs are very high, research and development time lengthening and operation easier strengthen.For two systems independently, in order to reach common control purpose, must upload the data on the daemon software separately, and data are handled respectively, combine carrying out function with other software or equipment then, also need hand inspection to handle in case of necessity.This method promptly enables to accomplish monitoring and control effect, and equipment can not well carry out trickle control.Inner at switch cubicle, the space is very limited, and switch cubicle inside must have safe distance except these two kinds of equipment also have other hardware devices between switch cubicle internal high pressure and other equipment, and this just makes the space more nervous.Two autonomous devices take certain hardware volume separately, the feasible insufficient space that other equipment are installed, even other equipment can't be installed.
The utility model content
The purpose of the utility model provides a kind of switch cubicle temperature and humidity monitor and; This device is with a switch cubicle temperature and humidity monitor and a system of state demonstration being integrated into; These two system's different pieces are made different functional, identical function is partly accomplished two different tasks with a utility module.Can reduce hardware cost like this, reduce operation easier, be convenient to management.Switch cubicle monitoring temperature and state show and combine; Can analyze both jointly and upload data; According to ambient temperature and humidity, monitoring switch cabinet contact humiture in external environment condition and the season environmental factor monitored in common switch cubicle, reach and more comprehensively control effect, make whole switch cubicle work more stable.
The purpose of the utility model realizes through following technical proposals.
Switch cubicle temperature and humidity monitor and; Comprise the control cubicle that connects some devices by a control board; And the repeater and the main website that are connected with this control cubicle, said control board is connected with contact humidity measuring transducer respectively, contact is measured temperature sensor, ambient temperature and humidity transducer, temperature humidity display and switch conformable display; Control board also is connected with electric supply installation.
Further, be connected with more than one contact humidity measuring transducer on the said control board respectively.
Further, be connected with more than one contact on the said control board respectively and measure temperature sensor.
The utility model is with functional similarity module in status display system and the contact humiture observation system: electric supply installation, ambient temperature and humidity transducer, control board, repeater, and main website software five parts; The functional module that the contact temperature measurement system is exclusive: plurality of contacts is measured temperature sensor, plurality of contacts humidity measuring transducer, Displaying Meter; The on off state display unit is exclusive: some on off state analysis circuits, temperature and humidity control circuit, on off state display floater functional module are combined into utility module; Dissimilar module is made a module separately; Form a new device; Thereby reach the minimizing hardware cost, reduce operation easier, the purpose of being convenient to manage.
