Description
Technical field
This utility model is related to technical field of electrical equipment, especially a kind of overvoltage-undervoltage protector.
Background technology
Overvoltage-undervoltage protector is conventional circuit protecting element, is frequently applied in electrical equipment or domestic power system
As a kind of protection device, when occur supply voltage too high or too low when, such as neutral in three phase and four wire circuit system
Broken string in line and the protection neutral conductor, it will lead to load-side neutral point excursion, when neutral point drift condition is serious, then single-phase
Loop will severe overvoltage or under-voltage, cause and burn individual event electrical equipment, or even jeopardize personal safety, now, for protective wire
The safety of the electrical appliance in road, it is to avoid work under abnormal power supply and lead to break down or damage, protector will cut off
Power supply.
Difference due to site environment makes it is sometimes necessary to be combined two or more overvoltage-undervoltage protectors
With, there is no any fixation due between adjacent two pressure-failure protectors, when vibrations than larger environment in it is easy to lead to owe
Pressure protector separates so that being connected to the wire deformation of pressure-failure protector, even results in wire dropping, and adjacent under-voltage guarantor
Shield device is not fixed, and installation and removal are troublesome.
Utility model content
The technical problems to be solved in the utility model is: cannot fix to solve existing adjacent two overvoltage-undervoltage protectors
Problem, this utility model provides a kind of overvoltage-undervoltage protector, and by arranging connecting hole on shell, pitman passes through connecting hole
Connect adjacent two overvoltage-undervoltage protectors, and by pasting area, adjacent two overvoltage-undervoltage protectors are pasted, thus effectively solving
The problem that existing adjacent two overvoltage-undervoltage protectors cannot be fixed.
This utility model solves its technical problem and be the technical scheme is that a kind of overvoltage-undervoltage protector, including shell,
The status indicator lamp being arranged on shell, the inlet wire screwed hole being used for fixing inlet wire and the outlet screwed hole for fixing outlet,
Also include the pitman for connecting adjacent two pressure-failure protectors, described shell is provided with least two companies running through shell both sides
Connect hole, described pitman is fixedly connected on connection in the hole, described shell both sides are provided with adjacent two overvoltage-undervoltage protectors of guarantee and fix
Firm stickup area.
Specifically, described pitman sets resilient anti-skid bulge it is ensured that pitman can be protected with adjacent two overvoltage/undervoltages
The connecting hole of shield device closely connects, and increases frictional force by raised, prevents from slipping.
Specifically, it is provided with the groove that insulation board placed by " t " type, adjacent described outlet spiral shell between adjacent described inlet wire screwed hole
It is provided with the groove that insulation board placed by " t " type between pit, prevent inlet wire to be short-circuited with outlet.
Specifically, described status indicator lamp includes overvoltage protection display lamp, run indicator, under-voltage protection display lamp and prolongs
When lamp, when voltage exceed tripping operation setting voltage when, delayed lamp flash, set delay time in magnitude of voltage just do not recover
Often, overvoltage-undervoltage protector tripping operation, overvoltage protection display lamp is bright；When voltage is less than the setting voltage of tripping operation, delayed lamp flashes,
In the delay time setting, magnitude of voltage does not recover normal, and overvoltage-undervoltage protector trips, and under-voltage protection display lamp is bright.
Specifically, the surface of described pitman is provided with skid resistant course, prevents pitman from slipping.
The beneficial effects of the utility model are: this utility model provides a kind of overvoltage-undervoltage protector, and structure is simple, can
Well two adjacent overvoltage-undervoltage protectors are fixed as one it is ensured that the stability that work, prevent overvoltage-undervoltage protector generation
Relative motion leads to access wire deformation, and makes installation and removal convenient after two adjacent overvoltage-undervoltage protectors are fixed,
Greatly save the time, improve work efficiency.

Specific embodiment
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with this utility model.
As shown in figure 1, a kind of overvoltage-undervoltage protector, including shell 1, the status indicator lamp 2 that is arranged on shell 1, it is used for
The inlet wire screwed hole 3 of fixing inlet wire and the outlet screwed hole 4 for fixing outlet, are also included for connecting adjacent two under-voltage protections
The pitman 5 of device, shell 1 is provided with least two connecting holes 6 running through shell 1 both sides, and pitman 5 is fixedly connected on connecting hole
In 6, shell 1 both sides are provided with the stickup area 7 ensureing that adjacent two overvoltage-undervoltage protectors are fixed.
Preferably, resilient anti-skid bulge 51 is set on pitman 5.
Preferably, being provided with the groove 8 that insulation board placed by " t " type, adjacent outlet screwed hole between adjacent inlet wire screwed hole 3
It is provided with the groove 8 that insulation board placed by " t " type between 4.
